     B.   Amendment

          1.   Section 1.1 of the Credit Agreement is
amended so that the definition of "Bank" and "Banks"
are amended to include PNC Bank, N.A.

          2.   Section 2.1 of the Credit Agreement is
amended so that the phrase "Two Hundred Sixty Million
Dollars ($260,000,000.00)" is deleted and the phrase
"Two Hundred Eighty Million Dollars ($280,000,000.00)"
is substituted in its place, each time it appears.

          3.   Section 2.2(a) of the Credit Agreement
is amended so that "$260,000,000" is deleted and
"$280,000,000" is substituted in its place.

          4.   The following are added as new
subsections (e) and (f) to Section 10.1 of the Credit
Agreement:

               "(e) which would release any material

                (f) which would increase the total
Commitments above $280,000,000."

          5.   Schedule 1 of the Credit Agreement is
deleted in its entirety and replaced by Schedule 1
attached hereto.

          6.   Schedule 3.1(d) and Schedule 4.11 to the
Credit Agreement are each amended to add the following:

          "Brazing Concepts Company, a Michigan
corporation"

          7.   The Schedule attached hereto as
Schedule 4.17 is attached to the Agreement as a new
Schedule 4.17.

     C.   Conditions.  The effectiveness of this
Agreement shall be conditioned upon the satisfaction of
the following conditions:

          1.   The Borrower shall have executed and
delivered to PNC Bank, N.A. a Revolving Note in the
maximum principal amount of $20,000,000.

          2.   Brazing Concepts Company shall have
executed and delivered to the Administrative Agent, for
the benefit of the Banks, an unlimited continuing
guaranty in form acceptable to the Administrative Agent
and the Banks, guarantying payment of any and all
indebtedness and obligations of the Borrower and/or the
Company to the Banks.

          3.   The Borrower and/or the Company shall
have paid all costs and expenses incurred by the
Administrative Agent and the Banks in connection with
the transactions contemplated by this Agreement
including, without limitation, reasonable attorney's
fees.

     D.   Other Provisions

          1.   By execution of this Agreement, each of
the Banks consents to the acquisition by Gibraltar of
the stock of Brazing Concepts Company and waives any
default under Section 6.7 of the Credit Agreement
resulting from such acquisition.

          2.   Except as specifically set forth herein,
the Credit Agreement shall remain in full force and
effect and is hereby reaffirmed.  The Borrower and the
Company acknowledge that they are bound by all of the
terms, covenants and conditions set forth in the Credit

Agreement, and that, if there has occurred any Default
or Event of Default, the Agent and the Banks shall have
no obligation to make any Advances or Swingloans or to
issue any Letters of Credit.  If there has occurred a
Default or an Event of Default, Agent and the Banks may
condition the making of any subsequent Advances or
Swingloans or the issuance of any Letters of Credit
upon the execution and delivery by Borrower and Company
of an amendment to the Credit Agreement which may
include, without limitation, additional or revised
covenants, an increased rate of interest on the
Revolving Credit, increased Letter of Credit or other
fees and such other terms, conditions and covenants as

          3.   The terms "Administrative Agent" and
"Banks" as used herein shall include the successors and
assigns of those parties and shall include PNC Bank,
N.A.

          4.   This Agreement shall be construed under,
and governed by, the internal laws of the State of New
York without regard to its conflict of laws and rules
which would make the laws of another jurisdiction
applicable.

          5.   This Agreement may be executed in any
number of counterparts, each of which when so executed
and delivered shall be an original, but all such
counterparts shall together constitute one and the same
Agreement.







             [This space intentionally left blank]

     IN WITNESS WHEREOF, the parties hereto have caused
this Agreement to be signed by their duly authorized
