ITEM 2.02    RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

     On May 11,  2005,  the  Registrant  issued  a press  release  revising  the
Registrant's  financial  results for the fiscal quarters ended December 31, 2004
and March 31, 2005. A copy of the Registrant's  press release is attached hereto
as Exhibit 99.1.

ITEM 4.02    NON-RELIANCE ON PREVIOUSLY ISSUED FINANCIAL STATEMENTS OR A RELATED
AUDIT REPORT OR COMPLETED INTERIM REPORT.

     (a)  On  May  10,  2005,  in  connection   with  the   preparation  of  the
          consolidated  financial  statements  for the second  quarter of fiscal
          2005, the Registrant ascertained that in the first quarter of the year
          there was an inventory  valuation error in determining the garage door
          segment's  cost of goods  sold.  This  inventory  valuation  error was
          caused by unprecedented  increases in the segment's raw material costs
          and  correction  of this error was included in the press release which
          previously  reported operating results for the second quarter of 2005.
          However, the Registrant has since determined to reflect the adjustment
          to  correct  cost  of  goods  sold  in the  first  quarter  of 2005 by
          restating that period's  operating  results.  The restatement will not
          change  previously  disclosed  earnings,   cash  flows,  or  financial
          position for the six months ended March 31, 2005 and will result in an
          estimated  $1,260,000  decrease  to bring  previously  reported  first
          quarter net income to $9,192,000 and a corresponding increase to bring
          second  quarter  net  income  to  $4,144,000.  First  quarter  diluted
          earnings per share will decrease  $.05 to an estimated  $.29 per share
          and second quarter diluted earnings per share will increase $.04 to an
          estimated $.13 per share.

          The  Registrant's  Chief Financial  Officer and the Audit Committee of
          the Board of Directors  discussed the matters disclosed in this filing
          with   PricewaterhouseCoopers   LLC,   the   Registrants   independent
          registered public accounting firm.

          As a  consequence  of  its  decision  to  restate  the  first  quarter
          financial  statements  the Registrant  reconsidered  its assessment of
          disclosure  controls  and  procedures  with a  focus  on  the  control
          deficiency (application of raw material purchase price variances) that
          did not sufficiently address the rising raw material costs. Reflecting
          the correction of the previously  issued  financial  statements in the
          quarter  ended March 31, 2005 would be  material to that  period,  and
          therefore,  the  Registrant  believes that a restatement  of the prior
          period interim financial statements is appropriate.  The impact of the
          inventory  valuation  error  on the  year  and  fourth  quarter  ended
          September  30, 2004 was not  material,  and  therefore was included as
          part of the  restatement  adjustment  made to cost of  goods  sold and
          inventory  for the quarter  ended  December  31,  2004.  However,  the
          Registrant  does not consider the effect of correcting  the previously
          issued  quarterly  financial  statements to be material to the interim
          period ended December 31, 2004 and thus has concluded that the control
          deficiency  that gave rise to the inventory  valuation  error does not
          constitute a material  weakness at December 31, 2004 or September  30,
          2004. Additionally,  the Registrant concluded that the error was not a
          material  weakness  at  March  31,  2005  because  additional  control
          procedures, including the timely review of raw material purchase price
          variances,  were implemented prior to March 31, 2005, which procedures
          are designed to provide  reasonable  assurance that such an error will
          not  recur.  Based on the above,  the  Registrant  concludes  that its
          disclosure controls and procedures were effective at March 31, 2005.


                                                                             2
