GN 817.4 indexing plungers are similar to GN 817, but with a T-handle instead of a round head knob. This shape allows better visual orientation of the indexing position of the Type C version, and is advantageous when greater unlocking forces occur.
Type C with rest position is used in 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.
For steel version see GN 817.4.
