Item 1.01.  Entry into a Material Definitive Agreement

On December 1, 2006, Mueller Industries, Inc. (the "Company") entered into a
Credit Agreement (the "Credit Agreement") among the Company (as borrower),
Lasalle Bank Midwest National Association ("Lasalle") (as agent) and certain
lenders (including Lasalle) named therein. The Credit Agreement replaces the
Company's prior credit agreement among the Company (as borrower), Lasalle (as
agent) and certain lenders (including Lasalle) named therein, dated as of
November 6, 2003 and amended as of September 27, 2004 and April 12, 2006.

The Credit Agreement provides for an unsecured $200 million revolving credit
facility, which matures in December 2011. The Company has the option to increase
the size of the credit facility to $250 million upon satisfaction of certain
conditions set forth in the Credit Agreement. Funds borrowed under the Credit
Agreement may be used by the Company for working capital, acquisitions and other
general corporate purposes.

Borrowings under the Credit Agreement bear interest, at the Company's option, at
(i) LIBOR plus a variable premium or (ii) the greater of Prime or the Federal
Funds rate plus 0.50 percent. LIBOR advances may be based upon the one, two, or
three-month LIBOR. The variable premium over LIBOR is based on certain financial
ratios, and can range from 27.5 to 67.5 basis points. Additionally, a facility
fee is payable quarterly on the aggregate amount of the commitments (whether
used or unused) and varies from 10.0 to 20.0 basis points based upon the
Company's capitalization ratio. Availability of funds under the credit facility
is reduced by the amount of certain outstanding letters of credit.

Borrowings under the Credit Agreement require the Company, among other things,
to meet certain minimum financial ratios. The Credit Agreement also contains
certain covenants relating to the Company's 6% Subordinated Debentures.

Amounts borrowed under the Credit Agreement by the Company are guaranteed on a
joint and several basis by certain of the Company's wholly-owned subsidiaries.

There is no material relationship between the Company and any of the parties to
the Credit Agreement other than in respect to the Credit Agreement and other
routine commercial banking services.

The description of the Credit Agreement contained herein is qualified in its
entirety by reference to the Credit Agreement, a copy of which is attached
hereto as Exhibit 10.1 and is incorporated herein by reference.


Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an
Off-Balance Sheet Arrangement of a Registrant
