PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, Bruce G. Blackey, certify that:

1.   I have reviewed this quarterly report on Form 10-Q of Clearfield, Inc.;

2.   Based on my knowledge,  this  quarterly  report does not contain any untrue
     statement of a material fact or omit to state a material fact  necessary to
     make the statements  made, in light of the  circumstances  under which such
     statements  were made, not misleading with respect to the period covered by
     this report;

3.   Based on my  knowledge,  the  financial  statements,  and  other  financial
     information  included in this  quarterly  report,  fairly  represent in all
     material respects the financial  condition,  results of operations and cash
     flows of the  registrant  as of, and for,  the  periods  presented  in this
     report;

4.   Clearfield,  Inc.'s other  certifying  officers and I are  responsible  for
     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules 13a and 15(e)) for Clearfield, Inc. and we have:

     a)   Designed  such  disclosure  controls  and  procedures  to ensure  that
          material  information  relating to  Clearfield,  Inc.,  including  its
          consolidated subsidiaries,  is made known to us by others within those
          entities, particularly during the period in which this report is being
          prepared;

     b)   Designed such internal  control over  financial  reporting,  or caused
          such internal  control over  financial  reporting to be designed under
          our  supervision,   to  provide  reasonable  assurance  regarding  the
          reliability  of financial  reporting and the  preparation of financial
          statements for external purposes in accordance with generally accepted
          accounting principles;

     c)   Evaluated the effectiveness of our disclosure  controls and procedures
          as of a date and presented in this  quarterly  report our  conclusions
          about the  effectiveness of the disclosure  controls and procedures as
          of the  end  of  the  period  covered  by  this  report  based  on our
          evaluation.

     d)   Disclosed  in this report any change in  Clearfield,  Inc.'s  internal
          control over financial  reporting that occurred during the most recent
          fiscal quarter that has materially  affected,  or is reasonably likely
          to materially affect, the Company's control over financial reporting.

5.   Clearfield, Inc.'s other certifying officers and I have disclosed, based on
     our most recent evaluation of internal control over financial reporting, to
     our auditors and the audit committee of our board of directors:

     a)   All significant  deficiencies and material weaknesses in the design or
          operation of internal  controls  over  financial  reporting  which are
          reasonably  likely to adversely affect  Clearfield,  Inc.'s ability to
          record, process, summarize and report financial information; and

     b)   Any fraud, whether or not material,  that involves management or other
          employees who have a  significant  role in the  registrant's  internal
          controls over financial reporting.
