Locking bolt with knob

If not operated, the plunger of the locking plungers GN 816 protrudes. To retract, move against the spring force and hold in the end position by turning by 90°. The shape of the cam curve secures the plunger against accidental operation. When operating the button (Type AR / ARK), the visible red covering sleeve indicates the locking status: Indexing pin does not protrude. For the execution with operation with key (Type B / BK) a key is required to move the plunger. In this execution, a cover sleeve provides additional security and safety from unauthorized removal of the locking plunger. The cover sleeve also provides additional protection against malfunction caused by dirt.
