Re:      Registration Statement on Form S-8 Relating to 1,600,000 Shares
         of the Common Stock, $.01 par value, of Kadant Inc.
         ---------------------------------------------------

Dear Sirs:

         I am General Counsel to Kadant Inc., a Delaware corporation (the
"Company"), and have acted as counsel in connection with the registration under
the Securities Act of 1933, as amended, on Form S-8 (the "Registration
Statement"), of 1,600,000 shares of the Company's Common Stock, $.01 par value
per share (the "Shares") subject to Company's Equity Incentive Plan (the
"Plan").

         I have reviewed the corporate proceedings taken by the Company with
respect to the authorization of the issuance of the Shares. I have also examined
and relied upon originals or copies, certified or otherwise authenticated to my
satisfaction, of all corporate records, documents, agreements or other
instruments of the Company and have made all investigations of law and have
discussed with the Company's representatives all questions of fact that I have
deemed necessary or appropriate.

         Based upon and subject to the foregoing, I am of the opinion that:

         1. The Company is a corporation validly existing and in corporate good
standing under the laws of the State of Delaware.

         2. The issuance and sale of the Shares as contemplated in the
Registration Statement have been duly authorized by the Company.

         3. The Shares, when issued and sold in accordance with the provisions
of the Plan, will be validly issued, fully paid and nonassessable.

         This opinion is limited to the applicable provisions of the Delaware
Constitution, the General Corporation Law of the State of Delaware ("Delaware
Law") and reported judicial decisions interpreting Delaware Law.

         I hereby consent to the filing of this opinion as Exhibit 5 to the
Registration Statement.

                                                           Very truly yours,



                                                           /s/ Sandra L. Lambert
