    RE: Registration Statement on Form S-4 Relating to $225,000,000 Aggregate
        Principal Amount of 10 1/8% Senior Subordinated Notes due 2012.

Ladies and Gentlemen:

     We have acted as special Louisiana counsel to Prager Incorporated, a
Louisiana corporation (the "LOUISIANA SUBSIDIARY"). In connection with the
registration of $225,000,000 aggregate principal amount of 10 1/8% Senior
Subordinated Notes due 2012 (the "SECURITIES") by Rexnord Corporation, a
Delaware Corporation (the "COMPANY"), and the guaranty of the Securities (the
"GUARANTY") by the Louisiana Subsidiary and numerous other guarantors (the
"ADDITIONAL GUARANTORS"), under the Securities Act of 1933, as amended (the
"ACT"), on Form S-4 filed with the Securities and Exchange Commission (the
"COMMISSION") on January 8, 2003 (File No. 333-_____) (the "REGISTRATION
STATEMENT"), you have requested our opinion with respect to the matters set
forth below. The Securities and the Guaranty will be issued pursuant to
an Indenture dated as of November 25, 2002 (the "INDENTURE") by and among the
Company, the Louisiana Subsidiary, the Additional Guarantors and Wells Fargo
Bank Minnesota, National Association, as Trustee (the "TRUSTEE"). The
Securities and the Guaranty will be issued in exchange for the Company's
outstanding 10 1/8% Senior Subordinated Notes due 2012 on the terms set forth
in the prospectus contained in the Registration Statement and the Letter of
Transmittal filed as an exhibit thereto. Unless otherwise defined herein,
terms defined in the Indenture and used herein shall have the meanings given
to them in the Indenture.

     We do not represent the Louisiana Subsidiary on general or regular basis
and, accordingly, have no detailed information concerning its business or
operations. Therefore, nothing contained herein should be construed as an
opinion regarding the Louisiana Subsidiary or its operations satisfying or
complying with any local laws or ordinances of general application pertaining
to the particular business and operations of the Louisiana Subsidiary.
