Item 7            Financial Statements and Exhibits.

          (c)  The following Exhibits are hereby filed as part of this Current
               Report on Form 8-K.

          99.1 Press Release issued by Mace Security International, Inc. dated
               May 12, 2003.

Item 9            Regulation FD Disclosure  (information  required by Item 12 of
                  Form 8-K is being furnished under this Item 9 pursuant to SEC
                  interim filing guidance dated March 27, 2003).

                  On May 12, 2003, Mace Security International, Inc. issued a
                  press release announcing its financial results for the fiscal
                  quarter ended March 31, 2003. A copy of the press release is
                  attached as Exhibit 99.1 and is incorporated herein by
                  reference in its entirety.

                  The press release contains a non-GAAP financial measure,
                  EBITDA. EBITDA is calculated as income before cumulative
                  effect of a change in accounting principle adding back
                  interest expense, income taxes, depreciation and amortization
                  expense. We believe that EBITDA, as presented, represents a
                  useful measure of assessing the performance of our operating
                  activities and resources available for strategic
                  opportunities, as it reflects our earnings trends, without the
                  impact of certain non-cash and unusual charges or income.
                  EBITDA is also used by our creditors in assessing debt
                  covenant compliance. We understand that, although security
                  analysts frequently use EBITDA in the evaluation of companies,
                  it is not necessarily comparable to other similarly titled
                  captions of other companies due to potential inconsistencies
                  in the method of calculation. EBITDA is not intended as an
                  alternative to cash flow provided by operating activities as a
                  measure of liquidity, as an alternative to net income as an
                  indicator of our operating performance, nor as an alternative
                  to any other measure of performance in conformity with
                  generally accepted accounting principles.
