GN 817 Indexing Plungers Steel, Lock-Out and Non Lock-Out, with Multiple Pin Lengths, with Red Knob


Product description


GN 817 indexing plungers with lock-out (type C / CK) are used for applications where the plunger pin needs to stay in its retracted position. To achieve this, the knob is rotated by 90 degrees after being retracted. A notch keeps the plunger in the retracted position.

This indexing plunger has the unique feature of the pull knob partially enclosing the top of the plunger body, allowing less debris to enter into the mechanism.
