# CERTIFICATION PURSUANT
TO 
SECTION 302(a) OF THE
SARBANES-OXLEY ACT OF 2002

I, Izhar Dekel:

1.
          I have reviewed this annual report on Form 20-F of Magal Security Systems Ltd.;

2.
          Based on my knowledge, this 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 report, fairly present 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.
          The registrants other certifying officer and I are responsible for
          establishing and maintaining disclosure controls and procedures (as defined in
          Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:

(a) Designed such disclosure controls
and procedures, or caused such disclosure controls and procedures to be designed under our
supervision, to ensure that material information relating to the registrant, 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 the registrants disclosure controls and procedures
and presented in this 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 such
evaluation; and (d) Disclosed in this report any change in the registrants internal
control over financial reporting that occurred during the period covered by the annual
report that has materially affected, or is reasonably likely to materially affect, the
registrants internal control over financial reporting; and

5.
          The registrants other certifying officer and I have disclosed, based on
          our most recent evaluation of internal control over financial reporting, to the
          registrants auditors and the audit committee of the registrants
          board of directors (or persons performing the equivalent function): (a) All
          significant deficiencies and material weaknesses in the design or operation of
          internal control over financial reporting which are reasonably likely to
          adversely affect the registrant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 control over financial reporting.
