Abstract
Abstract An instrument tray restraint having a replaceable magnetized bar. The restraint comprises a metal U-shaped channel into which a sterilizable flexible magnetized bar is inserted. The restraint is held onto a surgical instrument tray by tension clamps which facilitate easy attachment, removal, and adjustment of the restraint. The magnetized bar has a sufficient magnetic force to securely, yet releasably hold metallic surgical instruments onto the bar.
