Product description

Indexing plungers GN 817.2 are identical to GN 817 but with an extended height knob.

Lock-out types 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.
