                      POWER OF ATTORNEY

Know all by these presents, that the undersigned hereby constitutes and appoints
each of John L. Howard, David L. Rawlinson and Aimee M. Nolan, signing singly, the
undersigned's true and lawful attorney-in-fact to:

(1) execute for and on behalf of the undersigned Forms 3, 4, 5, and 144 relating
to equity securities of W.W. Grainger, Inc. (the "Company") in accordance with
Section 16(a) of the Securities Exchange Act of 1934 and the rules
thereunder and Rule 144 under the Securities Act of 1933;

(2) do and perform any and all acts for and on behalf of the undersigned which
may be necessary or desirable to complete any such Form 3, 4, 5, or 144 and
timely file the same with the United States Securities and Exchange
Commission and any stock exchange or similar authority; and

(3) take any other action of any type whatsoever in connection with the foregoing
which, in the opinion of the attorney-in-fact, may be of benefit to, in the best
interest of, or legally required by, the undersigned, it being understood that
the documents executed by the attorney-in-fact on behalf of the undersigned
pursuant to this Power of Attorney shall be in such form and shall contain
such terms and conditions as the attorney-in-fact may approve in his or her
discretion.

The undersigned hereby grants to each attorney-in-fact full power and authority to do
and perform any and every act and thing whatsoever requisite, necessary or proper to
be done in the exercise of any of the rights and powers herein granted, as fully to all
intents and purposes as the attorney-in-fact might or could do if personally present,
with full power of substitution or revocation, hereby ratifying and confirming all that the
attorney-in-fact, or his or her substitute or substitutes, shall lawfully do or cause to be
done by virtue of this Power of Attorney and the rights and powers herein granted.

The undersigned acknowledges that the attorneys-in-fact, in serving in such capacity
at the request of the undersigned, are not assuming, nor is the Company assuming,
any of the undersigned's responsibilities to comply with Section 16 of the Securities
Exchange Act of 1934 or Rule 144 under the Securities Act of 1933.

This Power of Attorney shall remain in full force and effect until the undersigned is no
longer required to file Forms 3, 4, 5, and 144 with respect to the undersigned's
holdings of and transactions in equity securities of the Company, unless earlier
