        RE:        Registration Statement on Form S-8 for 1998 Non-
                   Executive Long Term Incentive Plan

Gentlemen:

        We have acted as counsel to Tridex Corporation, a Connecticut
corporation (the "Company"), in connection with the filing by the Company of a
Registration Statement on Form S-8 (the "Registration Statement") with the
Securities and Exchange Commission relating to 600,000 shares of the Company's
common stock, no par value per share (the "Common Stock"), issuable under the
Tridex Corporation 1998 Non-Executive Long Term Incentive Plan (the "Plan").

        In connection with this opinion, we have examined the Company's Articles
of Incorporation, the bylaws of the Company, as amended, the Registration
Statement, corporate proceedings of the Company relating to the issuance of the
Common Stock, the Plan and such other instruments and documents as we have
deemed relevant under the circumstances.

        In making the aforesaid examination, we have assumed the genuineness of
all signatures and the conformity to original documents of all copies furnished
to us as original or photostatic copies.

        Based upon and subject to the foregoing, we are of the opinion that the
Common Stock which may be issued under the Plan has been duly authorized and
when issued in accordance with the terms of the Plan will be validly issued,
fully paid and non-assessable.

        We hereby consent to the use of our opinion as herein set forth as an 
exhibit to the Registration Statement. This opinion is rendered to you in
connection with the Registration Statement, and except as consented to in the
preceding sentence, may not be relied upon or furnished to any other person in
any context. In 


                                       27



giving such consent, we do not thereby admit that we are within the category of
persons whose consent is required under Section 7 of the Securities Act of 1933
or the rules and regulat ions of the Securities and Exchange Commission
thereunder.

                        Very truly yours,

                       /s/ Hinckley, Allen & Snyder
