POWER OF ATTORNEY

Know all by these presents, that the undersigned hereby constitutes and
appoints each of Nancy L. Berardinelli-Krantz, Paul Stanukinas, and
Cherita Thomas, signing singly, the undersigned's true and lawful
attorney-in-fact to:

(1)	execute for and on behalf of the undersigned a Form ID
(including amendments thereto), or any other forms prescribed by the
Securities and Exchange Commission, that may be necessary to obtain
codes and passwords enabling the undersigned to make electronic
filings with the Securities and Exchange Commission of the forms
referenced in clause (2)below;

(2)	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;

(3)	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

(4)	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 revoked by the undersigned in a
signed writing delivered to the attorneys-in-fact.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney
to be executed as of December 10, 2025, and revokes any previously
adopted power of attorney with respect to the rights and powers
herein granted.
