The portion supporting the padlock tab is yieldable such that force applied to the padlock tab will bend the support portion without allowing the more critical latch plate to bend.

Abstract: A method and apparatus for securing items in a storage unit comprise providing a cabinet with a plurality of drawers. Each drawer can be individually sealed by a break lock pull-tight security seal. As a security seal for a particular drawer is twisted and broken, items can then be obtained from the drawer. If a seal has been broken, a visual indication is made that the drawer has either been opened or tampered with. The inventory can thus be quickly and easily checked on a recurring basis without requiring each individual drawer to be checked since only drawers with broken seals need to be checked. The cabinets can be used to store pharmaceuticals, medical supplies, industrial supplies and/or any other supply for which an inventory must be maintained.
