Ladies and Gentlemen:

This opinion is rendered to you in connection with a registration statement (the
"Registration Statement") on Amendment No. 1 to Form S-4 as filed today
with the Securities and Exchange Commission under the Securities Act of 1933, as
amended, relating to the exchange offer (the "Exchange Offer") by Nortek, Inc.
("Nortek") and the subsidiary guarantors listed on Schedule I hereto (the
"Guarantors") to exchange (i) Nortek's $625,000,000 in aggregate principal
amount 8-1/2% Senior Subordinated Notes due 2014 (the "Exchange Notes") for
Nortek's outstanding $625,000,000 in aggregate principal amount 8-1/2%
Subordinated Notes due 2014 (the "Outstanding Notes") and (ii) the guarantees of
the Exchange Notes by the Guarantors (the "Exchange Guarantees") for the
guarantees of the Outstanding Notes by the Guarantors (the "Outstanding
Guarantees"). The Outstanding Notes and Outstanding Guarantees were issued
pursuant to the provisions of an indenture dated as of August 27, 2004 (the
"Indenture") entered into between Nortek, the Guarantors and U.S. Bank National
Association, a national banking association, as Trustee (the "Trustee").

We have acted as special counsel for Nortek and the Guarantors in connection
with the Exchange Offer and the preparation of the Registration Statement. For
purposes of this opinion, we have examined and relied upon the information set
forth in the Registration Statement and such other documents and records as we
have deemed necessary.

We express no opinion as to the laws of any jurisdiction other than those of the
State of New York, the General Corporation Law of the State of Delaware and the
federal laws of the United States of America.

Based upon the foregoing, we are of the opinion that:




1. When the Exchange Notes have been duly executed, authenticated and issued in
accordance with the provisions of the Indenture, and delivered against receipt
of the Outstanding Notes surrendered in exchange therefor upon completion of the
Exchange Offer, as described in the Registration Statement, the Exchange Notes
will constitute valid and binding obligations of Nortek, enforceable against
Nortek, in accordance with their terms and will be entitled to the benefits of
the Indenture.

2. When the Exchange Notes have been duly executed, authenticated and issued in
accordance with the provisions of the Indenture and have been delivered against
receipt of the Original Notes surrendered in exchange therefor upon completion
of the Exchange Offer, as described in the Registration Statement, and the
Exchange Guarantees have been duly executed and delivered in accordance with the
provisions of the Indenture, the Exchange Guarantees will constitute valid and
binding obligations of each of the Guarantors, enforceable against each
Guarantor in accordance with their terms and will be entitled to the benefits of
the Indenture.

Our opinions set forth above in paragraphs one and two with respect to the
enforceability of, and the obligations referred to in, the Exchange Notes and
the Exchange Guarantees are subject to (i) bankruptcy, insolvency,
reorganization or other similar laws affecting creditors' rights generally
(including, without limitation, Section 548 of Title 11 of The United States
Code and fraudulent conveyance or similar provisions of state law) and (ii)
general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

We hereby consent to the filing of this opinion as part of the Registration
Statement and to the use of our name therein and in the related prospectus under
the caption "Legal Matters."

Very truly yours,

/S/ Ropes & Gray LLP
