Accounting Policies [Abstract]
Background and Basis of Presentation	1. BACKGROUND AND BASIS OF PRESENTATION
	Background
	CommScope Holding Company, Inc., along with its direct and indirect subsidiaries (CommScope or the Company), is a global provider of essential infrastructure solutions for wireless, business enterprise and residential broadband networks. The Company’s solutions and services for wired and wireless networks enable high-bandwidth data, video and voice applications. CommScope’s global leadership position is built upon innovative technology, broad solution offerings, high-quality and cost-effective customer solutions and global manufacturing and distribution scale.
	In January 2015, the Company announced an agreement to acquire TE Connectivity’s Telecom, Enterprise and Wireless business, also referred to as Broadband Network Solutions (BNS), in an all-cash transaction valued at approximately $3.0 billion. This business provides fiber optic connectivity for wireline and wireless networks and generated annual revenues of approximately $1.9 billion in its fiscal year ended September 26, 2014. The acquisition is expected to be financed using a combination of cash on hand and approximately $2.75 billion of additional net debt. The transaction is expected to close by the end of 2015, subject to consummation of contemplated financing, regulatory approvals and other customary closing conditions. For the three months ended March 31, 2015, transaction and integration costs of $11.4 million, primarily related to the proposed acquisition, were included in selling, general and administrative expenses.
	Basis of Presentation
	The Condensed Consolidated Balance Sheet as of March 31, 2015, the Condensed Consolidated Statements of Operations and Comprehensive Income, Cash Flows and Stockholders’ Equity for the three months ended March 31, 2015 and 2014 are unaudited and reflect all adjustments of a normal recurring nature that are, in the opinion of management, necessary for a fair presentation of the interim period financial statements. The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for the full year.
	The unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and are presented in accordance with the applicable requirements of Regulation S-X. Accordingly, these financial statements do not include all of the information and notes required by U.S. GAAP for complete financial statements. The significant accounting policies followed by the Company are set forth in Note 2 within the Company’s audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 (the 2014 Annual Report). There were no changes in the Company’s significant accounting policies during the three months ended March 31, 2015. In addition, the Company reaffirms the use of estimates in the preparation of the financial statements as set forth in the audited consolidated financial statements. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements.
	Concentrations of Risk and Related Party Transactions
	Net sales to Anixter International Inc. and its affiliates (Anixter) accounted for 13% and 11% of the Company’s total net sales during the three months ended March 31, 2015 and 2014, respectively. Sales to Anixter primarily originate within the Enterprise segment. Other than Anixter, no other direct customer accounted for 10% or more of the Company’s total net sales for the three months ended March 31, 2015 or 2014.
	Accounts receivable from Anixter represented approximately 12% of accounts receivable as of March 31, 2015. Other than Anixter, no other direct customer accounted for more than 10% of the Company’s accounts receivable as of March 31, 2015.
	As of March 31, 2015, funds affiliated with The Carlyle Group owned 42.9% of the outstanding shares of CommScope.
	Product Warranties
	The Company recognizes a liability for the estimated claims that may be paid under its customer warranty agreements to remedy potential deficiencies of quality or performance of the Company’s products. These product warranties extend over periods ranging from one to twenty-five years from the date of sale, depending upon the product subject to the warranty. The Company records a provision for estimated future warranty claims as cost of sales based upon the historical relationship of warranty claims to sales and specifically-identified warranty issues. The Company bases its estimates on assumptions that are believed to be reasonable under the circumstances and revises its estimates, as appropriate, when events or changes in circumstances indicate that revisions may be necessary. Such revisions may be material.
	The following table summarizes the activity in the product warranty accrual, included in other accrued liabilities:
		Three Months Ended
		March 31,
		2015			2014
	Product warranty accrual, beginning of period	$	17,054		$	24,838
	Provision for warranty claims		1,542			2,269
	Warranty claims paid		(3,230	)		(4,169	)
	Product warranty accrual, end of period	$	15,366		$	22,938
	Commitments and Contingencies
	The Company is either a plaintiff or a defendant in pending legal matters in the normal course of business. Management believes none of these legal matters will have a material adverse effect on the Company’s business or financial condition upon final disposition.
	In addition, the Company is subject to various federal, state, local and foreign laws and regulations governing the use, discharge, disposal and remediation of hazardous materials. Compliance with current laws and regulations has not had, and is not expected to have, a materially adverse effect on the Company’s financial condition or results of operations.
	Asset Impairments
	Property, plant and equipment and intangible assets with finite lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable, based on the undiscounted cash flows expected to be derived from the use and ultimate disposition of the assets. Assets identified as impaired are carried at estimated fair value. There were no asset impairments identified during the three months ended March 31, 2015 or 2014.
	Income Taxes
	The effective income tax rate of 34.7% for the three months ended March 31, 2015 was lower than the statutory rate of 35% primarily due to the impact of earnings in foreign jurisdictions that the Company does not plan to repatriate. Such earnings are generally taxed at rates lower than the U.S. statutory rate. In addition, the effective income tax rate was also affected by the provision for state income taxes as well as losses in certain jurisdictions where the Company did not recognize tax benefits due to the likelihood of them not being realizable.
	The effective income tax rate of 36.9% for the three months ended March 31, 2014 was higher than the statutory rate of 35% primarily due to losses in certain jurisdictions where the Company did not recognize tax benefits due to the likelihood of them not being realizable, increases in valuation allowances on certain tax attributes, the provision for state income taxes and certain tax costs associated with repatriation of foreign earnings. These items were partially offset by benefits related to uncertain tax positions for which the statutes had lapsed and the $5.4 million pretax reduction in the estimated fair value of contingent consideration payable, which is not subject to tax.
	Earnings Per Share
	Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is based on net income divided by the weighted average number of common shares outstanding plus the dilutive effect of potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding equity-based awards (stock options, performance share units and restricted stock units). Certain outstanding equity-based awards were not included in the computation of diluted earnings per share because the effect was either antidilutive or the performance conditions were not met (1.3 million shares and 3.0 million shares for the three months ended March 31, 2015 and 2014, respectively).
	The following table presents the basis for the earnings per share computations:
		Three Months Ended
		March 31,
		2015			2014
	Numerator:
	Net income for basic and diluted earnings per share	$	39,476		$	64,487

	Dilutive effect of equity-based awards		4,657			4,980
	Weighted average common shares outstanding - diluted		193,137			190,922
	Earnings per share:
	Basic	$	0.21		$	0.35
	Diluted	$	0.2		$	0.34
	Recent Accounting Pronouncements
	In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-03, Simplifying the Presentation of Debt Issuance Costs. The ASU requires that debt issuance costs related to a recognized debt liability be reported as a direct deduction from the carrying amount of that debt liability. The Company will be required to adopt this guidance as of January 1, 2016 and apply it retrospectively to all prior periods presented. Early adoption is permitted. The adoption of this accounting guidance will reduce the Company’s other noncurrent assets and long-term debt by the amount of unamortized debt issuance costs. As of March 31, 2015 and December 31, 2014, this amount was $40.7 million and $43.2 million, respectively.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. This guidance defines how companies report revenues from contracts with customers, and also requires enhanced disclosures. The Company will be required to adopt the standard as of January 1, 2017 and early adoption is not permitted. In April 2015, the FASB announced a proposal to defer the effective date by one year, with early adoption on the original effective date permitted. The Company has not determined the transition approach that will be utilized or estimated the impact of adopting the new accounting standard.

Acquisitions

Business Combinations [Abstract]
Acquisitions	2. ACQUISITIONS
	Alifabs Group
	In July 2014, the Company acquired two businesses of United Kingdom-based Alifabs Group (Alifabs) for $48.8 million ($46.7 million, net of cash acquired). Alifabs is a designer and supplier of enclosures, monopoles, smaller streetworks towers and tower solutions for the United Kingdom telecommunications, utility and energy markets. Sales of Alifabs products reflected in the Condensed Consolidated Statements of Operations and Comprehensive Income were $11.2 million for the three months ended March 31, 2015.
	The preliminary allocation of the purchase price, based on estimates of the fair values of assets acquired and liabilities assumed, is as follows (in millions):
	Cash and cash equivalents	$	2.1
	Other current assets		15.7
	Identifiable intangible assets		26.9
	Goodwill		15.3
	Other noncurrent assets		0.6
	Less: Liabilities assumed		(11.8	)
	Net acquisition cost	$	48.8
	The goodwill arising from the purchase price allocation of the Alifabs acquisition is believed to result from the company’s reputation in the marketplace and assembled workforce and is not expected to be deductible for income tax purposes.
	As additional information is obtained, adjustments may be made to the preliminary purchase price allocation. The Company is still finalizing the estimated fair value of certain assets acquired and liabilities assumed.
	Redwood Systems, Inc.
	In July 2013, the Company acquired Redwood Systems, Inc. (Redwood), for an initial payment of $9.8 million and contingent consideration payable in 2015 that had an estimated fair value of $12.4 million as of the acquisition date. During the year ended December 31, 2014, the estimated fair value of the liability for contingent consideration was reduced to zero and no payments are expected to be made.
	iTRACS Corporation
	In March 2013, the Company acquired substantially all the assets and certain liabilities of iTRACS Corporation (iTRACS) for $34.0 million. In March 2014, the Company reached an agreement with the former owners of iTRACS to adjust the purchase price by $4.7 million and that amount was received by the Company in April 2014.

	Senior Secured Credit Facilities
	During the three months ended March 31, 2015, the Company repaid $2.2 million of its senior secured term loans. No portion of the senior secured term loans was reflected as a current portion of long-term debt as of March 31, 2015 related to the potentially required excess cash flow payment because the amount that may be payable in 2016, if any, cannot currently be reliably estimated. There was no excess cash flow payment required in 2015 related to 2014.
	During the three months ended March 31, 2015, the Company did not borrow under its revolving credit facility. As of March 31, 2015, the Company had availability of approximately $283.9 million under the asset-based revolving credit facility, after giving effect to borrowing base limitations and outstanding letters of credit.
	Other Matters
	The Company’s non-guarantor subsidiaries held approximately $1,092 million, or 22%, of total assets and approximately $265 million, or 7%, of total liabilities as of March 31, 2015 and accounted for approximately $375 million, or 45%, of net sales for the three months ended March 31, 2015. As of December 31, 2014, the non-guarantor subsidiaries held approximately $1,089 million, or 22%, of total assets and approximately $282 million, or 8%, of total liabilities. For the three months ended March 31, 2014, the non-guarantor subsidiaries accounted for approximately $320 million, or 34%, of net sales. All amounts presented exclude intercompany balances.
	CommScope, Inc., a subsidiary of the Company, is the issuer of the senior notes. The reported balance sheet and income statement amounts for CommScope, Inc. are substantially identical to those of the Company other than interest expense for CommScope, Inc. for the three months ended March 31, 2015 and 2014 which does not reflect the interest expense incurred in connection with the senior PIK toggle notes, which was $9.5 million for both periods ($6.1 million net of tax). Total debt for CommScope, Inc. as of March 31, 2015 was $2,156.1 million, which does not include the senior PIK toggle notes.
	The weighted average effective interest rate on outstanding borrowings, including the amortization of debt issuance costs and original issue discount, was 5.38% at both March 31, 2015 and December 31, 2014.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	6. DERIVATIVES AND HEDGING ACTIVITIES
	The Company uses forward contracts to hedge a portion of its exposure to balances denominated in currencies other than the functional currency of various subsidiaries and to manage exposure to certain planned foreign currency expenditures in order to mitigate the impact of changes in exchange rates. As of March 31, 2015, the Company had foreign exchange contracts with maturities of up to nine months with an aggregate notional value of $318 million (based on exchange rates as of March 31, 2015). Unrealized gains and losses resulting from these contracts are recognized in other income (expense), net and partially offset corresponding foreign exchange gains and losses on the balances being hedged. These instruments are not held for speculative or trading purposes. These contracts are not designated as hedges for hedge accounting and are marked to market each period through earnings.
	The following table presents the balance sheet location and fair value of the Company’s derivatives:

Restructuring and Related Activities [Abstract]
Restructuring Costs	9. RESTRUCTURING COSTS
	The Company has initiated restructuring actions to realign and lower its cost structure primarily through workforce reductions and other cost reduction initiatives at various facilities, including the cessation of manufacturing operations at the Joliet, Illinois; Statesville, North Carolina; and Guangzhou, China facilities. Much of the production capacity from these facilities has been shifted to other existing facilities or unaffiliated suppliers.
	The Company’s net pretax restructuring charges, by segment, were as follows:

	Other noncurrent liabilities		—			6,117			—			6,117
	Total liability	$	3,324		$	7,812		$	—		$	11,136
	Employee-related costs include the expected severance costs and related benefits as well as one-time severance benefits that are accrued over the remaining period employees are required to work in order to receive such benefits.
	Lease termination costs relate to the discounted cost of unused leased facilities, net of anticipated sub-rental income.
	Fixed asset related costs include non-cash impairments or disposals of fixed assets associated with restructuring actions in addition to the cash costs to uninstall, pack, ship and reinstall manufacturing equipment and the costs to prepare the receiving facility to accommodate relocated equipment. These costs are expensed as incurred. Cash paid is net of proceeds received from the sale of related assets.
	As a result of restructuring and consolidation actions, the Company owns unutilized real estate at various facilities in the U.S. and internationally. The Company is attempting to sell or lease this unutilized space. Additional impairment charges may be incurred related to these or other excess assets.
	Additional pretax costs of approximately $1.0 million to $2.0 million are expected to complete these initiatives. Cash payments of approximately $4.0 million to $5.0 million are expected to be paid by the end of 2015 with additional payments of $8.0 million to $9.0 million to be paid between 2016 and 2022. Additional restructuring actions may be taken and the resulting charges and cash requirements could be material.

	Equity-Based Compensation Plans
	As of March 31, 2015, $44.9 million of total unrecognized compensation costs related to non-vested stock options, restricted stock unit awards (RSUs), performance share units (PSUs) and share unit awards are expected to be recognized over a remaining weighted average period of 1.9 years. Although the share unit awards may, at the Company’s discretion, be settled in stock, they have historically been settled in cash and are accounted for as liability awards. There were no significant capitalized equity-based compensation costs at March 31, 2015.
	Stock Options
	Stock options are awards that allow the recipient to purchase shares of the Company’s common stock at a fixed price. Stock options are granted at an exercise price equal to the Company’s stock price at the date of grant. These awards generally vest over one to five years following the grant date and have a contractual term of ten years.

	$2.96 to $30.76		9,113			5.9		$	7.99		7,319	$	7.53
	The Company uses the Black-Scholes model to estimate the fair value of stock option awards. Key input assumptions used in the model include the grant date fair value of common stock, exercise price of the award, the expected option term, stock price volatility, the risk-free interest rate and the Company’s projected dividend yield. The Company believes that the valuation technique and the approach utilized to develop the underlying assumptions are appropriate in estimating the fair values of its stock options. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive equity awards. Subsequent events are not indicative of the reasonableness of the original estimates of fair value made by the Company. The following table presents the weighted average assumptions used to estimate the fair value of stock option awards granted.

	Weighted average fair value at grant date	$	13.25		$	9.4
	Performance Share Units
	PSUs are stock awards in which the number of shares ultimately received by the employee depends on Company performance against specified targets. Such awards vest and shares are issued over three years if the performance targets are met. The fair value of each PSU is determined on the date of grant, based on the Company’s stock price. Over the performance period, the number of shares that are expected to be issued is adjusted upward or downward based upon the probable achievement of performance targets. The ultimate number of shares issued and the related compensation cost recognized will be based on the final performance metrics compared to the targets specified in the grants.
	The following table summarizes the PSU activity (in thousands, except per share data):

Basis of Presentation	Basis of Presentation
	The Condensed Consolidated Balance Sheet as of March 31, 2015, the Condensed Consolidated Statements of Operations and Comprehensive Income, Cash Flows and Stockholders’ Equity for the three months ended March 31, 2015 and 2014 are unaudited and reflect all adjustments of a normal recurring nature that are, in the opinion of management, necessary for a fair presentation of the interim period financial statements. The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for the full year.
	The unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and are presented in accordance with the applicable requirements of Regulation S-X. Accordingly, these financial statements do not include all of the information and notes required by U.S. GAAP for complete financial statements. The significant accounting policies followed by the Company are set forth in Note 2 within the Company’s audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 (the 2014 Annual Report). There were no changes in the Company’s significant accounting policies during the three months ended March 31, 2015. In addition, the Company reaffirms the use of estimates in the preparation of the financial statements as set forth in the audited consolidated financial statements. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements.

	The Company recognizes a liability for the estimated claims that may be paid under its customer warranty agreements to remedy potential deficiencies of quality or performance of the Company’s products. These product warranties extend over periods ranging from one to twenty-five years from the date of sale, depending upon the product subject to the warranty. The Company records a provision for estimated future warranty claims as cost of sales based upon the historical relationship of warranty claims to sales and specifically-identified warranty issues. The Company bases its estimates on assumptions that are believed to be reasonable under the circumstances and revises its estimates, as appropriate, when events or changes in circumstances indicate that revisions may be necessary. Such revisions may be material.
	The following table summarizes the activity in the product warranty accrual, included in other accrued liabilities:
		Three Months Ended
		March 31,
		2015			2014
	Product warranty accrual, beginning of period	$	17,054		$	24,838
	Provision for warranty claims		1,542			2,269
	Warranty claims paid		(3,230	)		(4,169	)
	Product warranty accrual, end of period	$	15,366		$	22,938
Commitments and Contingencies	Commitments and Contingencies
	The Company is either a plaintiff or a defendant in pending legal matters in the normal course of business. Management believes none of these legal matters will have a material adverse effect on the Company’s business or financial condition upon final disposition.
	In addition, the Company is subject to various federal, state, local and foreign laws and regulations governing the use, discharge, disposal and remediation of hazardous materials. Compliance with current laws and regulations has not had, and is not expected to have, a materially adverse effect on the Company’s financial condition or results of operations.
Asset Impairments	Asset Impairments
	Property, plant and equipment and intangible assets with finite lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable, based on the undiscounted cash flows expected to be derived from the use and ultimate disposition of the assets. Assets identified as impaired are carried at estimated fair value. There were no asset impairments identified during the three months ended March 31, 2015 or 2014.
Income Taxes	Income Taxes
	The effective income tax rate of 34.7% for the three months ended March 31, 2015 was lower than the statutory rate of 35% primarily due to the impact of earnings in foreign jurisdictions that the Company does not plan to repatriate. Such earnings are generally taxed at rates lower than the U.S. statutory rate. In addition, the effective income tax rate was also affected by the provision for state income taxes as well as losses in certain jurisdictions where the Company did not recognize tax benefits due to the likelihood of them not being realizable.
	The effective income tax rate of 36.9% for the three months ended March 31, 2014 was higher than the statutory rate of 35% primarily due to losses in certain jurisdictions where the Company did not recognize tax benefits due to the likelihood of them not being realizable, increases in valuation allowances on certain tax attributes, the provision for state income taxes and certain tax costs associated with repatriation of foreign earnings. These items were partially offset by benefits related to uncertain tax positions for which the statutes had lapsed and the $5.4 million pretax reduction in the estimated fair value of contingent consideration payable, which is not subject to tax.
Earnings Per Share	Earnings Per Share
	Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is based on net income divided by the weighted average number of common shares outstanding plus the dilutive effect of potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding equity-based awards (stock options, performance share units and restricted stock units). Certain outstanding equity-based awards were not included in the computation of diluted earnings per share because the effect was either antidilutive or the performance conditions were not met (1.3 million shares and 3.0 million shares for the three months ended March 31, 2015 and 2014, respectively).
	The following table presents the basis for the earnings per share computations:
		Three Months Ended
		March 31,
		2015			2014

	Net income for basic and diluted earnings per share	$	39,476		$	64,487

Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-03, Simplifying the Presentation of Debt Issuance Costs. The ASU requires that debt issuance costs related to a recognized debt liability be reported as a direct deduction from the carrying amount of that debt liability. The Company will be required to adopt this guidance as of January 1, 2016 and apply it retrospectively to all prior periods presented. Early adoption is permitted. The adoption of this accounting guidance will reduce the Company’s other noncurrent assets and long-term debt by the amount of unamortized debt issuance costs. As of March 31, 2015 and December 31, 2014, this amount was $40.7 million and $43.2 million, respectively.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. This guidance defines how companies report revenues from contracts with customers, and also requires enhanced disclosures. The Company will be required to adopt the standard as of January 1, 2017 and early adoption is not permitted. In April 2015, the FASB announced a proposal to defer the effective date by one year, with early adoption on the original effective date permitted. The Company has not determined the transition approach that will be utilized or estimated the impact of adopting the new accounting standard.
