                                      TO
                               CREDIT AGREEMENT

This Third Amendment to Credit Agreement (this "Third Amendment"), dated as 
of December 18, 1996, is among Michigan National Bank, a national banking 
association, and the other banking institutions listed on Exhibit A 
attached hereto and who appear as signatories to this Third Amendment (each 
a "Bank" and collectively the "Banks"), Michigan National Bank, as agent 
("Agent"), and Mueller Industries, Inc., a Delaware corporation 
("Borrower").

                                   Recitals

The Agent, the Borrower and some of the Banks executed a certain Credit 
Agreement (the "Credit Agreement") dated as of June 1, 1994, providing for, 
among other things, the establishment by the Banks for the benefit of the 
Borrower of a line of credit in the amount of $30,000,000.  The Credit 
Agreement was amended by a First Amendment to Credit Agreement, dated as of 
December 14, 1994, and by a Second Amendment to Credit Agreement, dated as 
of June 1, 1995 (the Credit Agreement, as so amended, the "Amended Credit 
Agreement").

The Borrower has now requested the Banks to consider certain amendments to 
the Amended Credit Agreement, including an increase in the aggregate 
principal amount of the loans that can be outstanding at any one time to 
$100,000,000.00, as well as certain changes in the identity of the banks 
that are to be parties to the Credit Agreement, and the Banks have 
consented to such amendments as set forth herein upon the terms and 
conditions set forth herein.

Capitalized terms used but not defined herein shall have the meanings 
ascribed to them in the Amended Credit Agreement.
