Borgbout met T-greep en borgmoer

Stainless steel 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 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.
