Re:  Registration Statement for 750,000 Shares of Common Stock to be issued
     pursuant to Clearfield, Inc. 2007 Stock Compensation Plan Our File No.
     16619-1

Gentlemen:

     This opinion is given in connection with the filing by Clearfield, Inc.
(the "Registrant") with the Securities and Exchange Commission under the
Securities Act of 1933, of a Registration Statement on Form S-8 (the
"Registration Statement"), with respect to 750,000 shares of the Registrant's
Common Stock, $.01 par value (the "Shares"), that may be issued upon exercise of
options or other awards that have been or may be granted under the Registrant's
2007 Stock Compensation Plan (the "Plan").

     We have acted as counsel for the Registrant in connection with the filing
of the Registration Statement. In so acting, we have examined the originals or
copies, certified or otherwise identified to our satisfaction, of all corporate
instruments and have made such inquiries of officers and representatives of the
Registrant as we have deemed relevant and necessary as a basis for the opinion
hereinafter set forth. In such examination, we have assumed the genuineness of
all signatures and the authenticity of all documents submitted to us as
originals and the conformity to the original of documents submitted to us as
certified or photostatic copies. As to questions of fact material to such
opinion that we have not independently established, we have relied upon
representations or certificates of officers and directors of Registrant.



<PAGE>


      Based upon the foregoing, we are of the following opinion:

      1.    The Registrant has been duly incorporated and is validly existing as
            a corporation under the laws of the State of Minnesota.

      2.    The Shares have been duly authorized and when issued and delivered
            as contemplated under the Plan will be validly issued and
            outstanding, fully paid and nonassessable.

      We consent to the use of this opinion as an exhibit to the Registration
Statement. We further consent to the use of this opinion as an exhibit to
applications to the securities commissioners of various states of the United
States for registration therein of various aggregate amounts of the Shares.


Very truly yours,

/s/ Messerli & Kramer P.A.
