Information

Lockable Stainless Steel-Indexing plungers GN 814 are used for applications where unauthorized operation is to be prevented. Types A and AK secure the plunger pin in the front position after locking. Types E and EK additionally secure the plunger pin in the rear position if it is not to protrude temporarily.

The key can be removed in the end positions. Locks with coding SC are keyed alike, allowing each lock to be operated with the same key. Locks with coding SU have different locks with 68 different lock versions and correspondingly numbered keys.

For assembly, the indexing plunger can be screwed in or out via a hexagon socket, which is only accessible when the knob is pulled back. If necessary, lock nuts should be additionally secured against manipulation, e.g. by gluing or welding.
