These spring loaded hand retractable plungers are used to prevent any change in locking position due to lateral force. Pulling up on the handle retracts the plunger pin into the body. The locking style allows the plunger to remain in the retracted position. The short body allows the plungers to be used in confined spaces. The body is made from stainless steel with a natural finish. Plungers are supplied with a jam nut. The knob is made from black plastic. Plungers without jam nuts are also available.
