Clamping levers GN 99.2 are known for their small dimensions.
They are for use in applications where either the clamping range is limited or where a specific lever position is required. The serrated bore in the spherical hub is fitted with a threaded bolt insert which engages in the hub with its own serrations.
By depressing the clamping lever the serrations are disengaged freeing it for re-positioning in the most convenient position. When releasing the lever the serrations will re-engage automatically.
Should a rotation of 360° not be possible the insert can be slightly screwed in (after the lever has been disengaged) by means of the slotted knurled screw.
