GN99.2 Adjustable Clamping Lever, Push to Disengage, Threaded Insert.
These adjustable clamping levers have small dimensions 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 repositioning 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.
