Heavy Duty Adjustable Tension Levers GN212.3 have
proven to be ideal wherever parts have to be clamped in
a confined space, or if a particular lever position is re-
quired. The threaded insert is connected with the hub via
serrations which can be disengaged.
Pulling the lever upward disengages the serrations,
allowing it to be swivelled to the best clamping position.
On releasing the lever it will automatically re-engage.
Tension levers non-adjustable, see GN 212.
Special threads and stud lengths are available upon
request.
Straight version in inch sizes available upon request.
