GN817.4 Indexing Plungers, with T Handle, Steel
These indexing plungers are similar to GN817, 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 advantageous 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.
Steel ST - blackened
Plunger - hardened
T-Handle - Plastic (Polyamide PA), not removable, black, matt.
Also available in stainless steel
