Prevent any change in locking position due to lateral force. These spring loaded hand retractable plungers are used to prevent any change in locking position due to lateral force. Pulling up on the L handle retracts the plunger pin into the body. By turning the handle while in the retracted position, the plunger can be locked in the retracted position. The body and plunger are made from alloy steel with blue chromate finish.
