Re:  Registration Statement on Form S-4 of Kevco, Inc. and subsidiaries
     ------------------------------------------------------------------


Gentlemen:
    
We are acting as counsel for Kevco, Inc., a Texas corporation and its
subsidiaries (the "Company"), in connection with the registration under the
Securities Act of 1933, as amended (the "Act"), of the offer and sale of up to
$105,000,000 of 10 3/8% Senior Subordinated Notes due 2007 with the related
subsidiary guarantees (the "Exchange Notes") in exchange for the Company's 10
3/8% Senior Subordinated Notes due 2007 (the "144A Notes") issued in a private
placement pursuant to Rule 144A under the Act, as contemplated by the Company's
Registration Statement on Form S-4, which we understand is expected to be filed
with the Securities and Exchange Commission (the "Commission") on or about the
date hereof (as amended, the "Registration Statement").    

In reaching the conclusions expressed in this opinion we have examined and
relied on such documents, corporate records and other instruments, including the
Indenture (the "Indenture") dated as of December 1, 1997 between the Company,
the Company's subsidiary guarantors and the United States Trust Company of New
York, N.A. as trustee (the "Trustee") pursuant to which the Exchange Notes are
to be issued, Supplemental Indentures dated as of December 1, 1997, each between
the Trustee and a subsidiary of the Company that was not a party to the
Indenture (the Indenture with the Supplemental Indentures are hereinafter
referred to as the "Indenture"), certificates of public officials and
certificates of officers of the Company, and made such further investigation and
inquiry as we have deemed necessary to reach the opinions expressed herein.  In
making the foregoing examinations, we have assumed the genuineness of all
signatures on original documents, the authenticity, accuracy and completeness of
all documents submitted to us as originals and the conformity to original
documents of all copies submitted to us.

Based solely upon the foregoing, subject to the comments and exceptions
hereinafter stated, it is our opinion that:

 
     1.   The Exchange Notes have been duly authorized by all necessary
corporate action on the part of the Company.

    
     2.   Subject to the Registration Statement becoming effective under the
Act, to the Indenture being qualified under the Trust Indenture Act
of 1939, as amended, to compliance with any applicable state securities laws,
and to the Exchange Notes being executed by the Company and authenticated by the
Trustee in accordance with the terms of the Indenture, the Exchange Notes
proposed to be exchanged by the Company for the 144A Notes pursuant to the terms
of the exchange offer described in the Registration Statement have been duly
authorized for issuance and, when issued and delivered in exchange for the 144A
Notes in accordance with the terms and provisions of the exchange offer as
described in the Registration Statement and the Indenture, will be entitled to
the benefits of the Indenture and will be valid and legally binding obligations
of the Company, enforceable against the Company in accordance with their terms,
except as enforceability thereof may be limited by (a) bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance or other similar laws relating
to or affecting creditors' rights generally and (b) by general principles of
equity (regardless of whether such enforceability is considered in a proceeding
in equity or at law).     

    
Our opinion is further subject to the qualification that certain of the waivers
and remedies in the Indenture and the Exchange Notes may be unenforceable under,
or may be limited by, the laws (including judicial decisions) of the State of
New York and the United States. However, the unenforceability or limitation of
such covenants, waivers and remedies will not, in our opinion, prevent the
substantial realization by the holders thereof of the practical benefits
intended to be provided by the Indenture and the Exchange Notes, except for the
economic consequences of any delay that may result from such enforceability or
limitation.     

    
We express no opinion as to the laws of any jurisdiction other than the law of
the state of Texas, the General Corporation Law of the State of Delaware,
applicable federal laws of the United States of America and the contract law of
the State of New York, in each case as in effect on the date hereof.     

We hereby consent to the use of this opinion as an exhibit to the Registration
Statement and to the reference to our firm therein under the caption "Legal
Matters." In giving this consent, we do not admit that we come within the
category of persons whose consent is required under Section 7 of the Act or the
rules and regulations of the Commission promulgated thereunder.

Very truly yours,



/s/ Jackson Walker L.L.P.
