Mini indexing plungers, covered indexing mechanism, with red knob

Mini indexing plungers GN 822 are distinguished for their small dimensions. They have been designed for installation in thin walled sheet metal constructions.
They are inserted into position by holding them by the serrated knob. The spanner flats on the lock nut are revealed when retracting the pin, so that the mini indexing plunger can be easily tightened by means of a fork spanner.
With type C the knob can be turned by 30° and a notch keeps the knob in this position.
