||GN 822 indexing plungers
feature small, compact dimensions. They are designed for installation
in thin walled sheet metal applications.
Plungers are inserted into position by holding them by the knurled
knob. The wrench flats on the lock nut are exposed when the
pin is retracted, so that the plunger can be easily tightened
by means of an open end wrench.
Type B is non lock-out type.
Type C offers a lock-out position for applications that require the plunger pin to be retracted for an extended period of time.
In the rest position, the lock-out mechanism is completely concealed by the knob.
