Re:	TriMas Corporation
	Registration Statement on Form S-3
	File No. 333-

Ladies and Gentlemen:

We have acted as counsel for TriMas Corporation, a Delaware corporation (the “Company”) in connection with the preparation and filing of a registration statement on Form S-3 (the “Registration Statement”) relating to the registration under the Securities Act of 1933, as amended (the “Act”), of up to 3,500,000 shares of common stock, $0.01 par value, plus an indeterminate number of shares of common stock that may be issued upon stock splits, stock dividends or similar transactions in accordance with Rule 416 of the Act, of the Company (the “Shares”) which may be offered and sold by the selling stockholder named therein.

This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act.

In rendering the opinion set forth herein, we have examined originals, photocopies or conformed copies certified to our satisfaction of all such corporate records, agreements, instruments and documents of the Company, certificates of public officials and other certificates and opinions, and we have made such other investigations, as we have deemed necessary in connection with the opinions set forth herein.  In our examinations, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to originals of all documents submitted to us as photocopies or conformed copies.

We advise you that, based upon and subject to the foregoing, we are of the opinion that the Shares mentioned above were duly authorized and such Shares represent validly issued, fully paid and non-assessable shares of the Company’s common stock.

In rendering this opinion we express no opinion as to the laws of any jurisdiction other than the Delaware General Corporation Law (including the statutory provisions, all applicable provisions of the Delaware Constitution and reported judicial decisions interpreting the foregoing).

We hereby consent to the use of our name under the caption “Legal Matters” in the prospectus included in the Registration Statement and to the filing of a copy of this opinion with the Securities and Exchange Commission as an exhibit to the Registration Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Securities and Exchange Commission thereunder.

Very truly yours,

/s/ CAHILL GORDON & REINDEL LLP
