Dear Sirs:
 
     I am familiar with the ITT Industries Investment and Savings Plan for
Salaried Employees (the "Investment and Savings Plan") of ITT Industries, Inc.,
an Indiana corporation ("ITT Industries"), under which 6,000,000 shares of ITT
Industries common stock, par value $1 per share, have been authorized initially
for issuance (the "Shares"). I have acted as counsel to ITT Industries in
connection with the preparation and filing with the Securities and Exchange
Commission under the Securities Act of 1933, as amended (the "Act"), of
Post-Effective Amendment No. 7 to Registration Statement on Form S-8 (the
"Registration Statement") with respect to the registration under the Act of the
Shares. In this connection, I have examined such records, documents and
proceedings as I have deemed relevant and necessary as a basis for the opinion
expressed herein.
 
     Based upon the foregoing, I am of the opinion that Shares have been duly
authorized for issuance under the Investment and Savings Plan by all proper
corporate action and, when such Shares have been issued pursuant to the
provisions of the Investment and Savings Plan as set forth in the Registration
Statement and ITT Industries' policies relating thereto, and any conditions or
restrictions relating thereto shall have been satisfied, such Shares will be
legally issued, fully paid and non-assessable.
 
     I hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement.
 
                                  Very truly yours,
 

                                  /s/ ROBERT W. BEICKE
                                      Robert W. Beicke
                                      Vice President, Associate General Counsel
                                      and Assistant Secretary
