Information

Indexing plungers GN 817.4 are similar to GN 817 but with a T-handle instead of a round head.

This shape allows better visual orientation of the indexing position of Type C and is advantageouse when greater unlocking forces occur.

Type C with rest position is used in such applications where the plunger must not protrude continually. In that case the knob is retracted and afterwards turned by 90°. A notch keeps the plunger in this position.
