General information

Features and applications

GN 816 indexing plungers are protruding in the rest position. By pulling the plunger inside the body and turning the knob by 90°, the plunger reaches the retracted safety position by means of the pin sliding inside a slit. The plunger returns into the original protruding position by pulling once again the knob, making it turn by 90° and releasing it.

For GN 816-B and GN 816-BK the above operations may be carried out only by means of a key (to be ordered separately).

Supplied with the technopolymer sleeve not assembled. It can be assembled eventually by a simple pressure.
