These are smaller versions of the full-size Bessey auto-adjust
toggle clamps (our item #17F72.01).
They automatically accommodate
material thickness changes (up to 13/16", or 3/8" for the
in-line clamps) without altering the clamping force, eliminating
the need for frequent adjustment. Available with a regular flat
mounting base, as well as with a center-flange or perpendicular
base that lets you mount the clamp on the edge of a clamping
The in-line clamp has an 11/16" throw; the flat-mount horizontal clamp has a 3/4" center height, and the perpendicular-mount clamp can be mounted for center heights
between 11/16" and 1-3/16".
The flat-mount and center-flange clamps can accommodate
stock up to 1-3/16" thick; the perpendicular-mount clamp has
a 1-7/16" capacity. The vertical clamp has a 13/16" capacity.
Each has a knurled screw to adjust the
clamping force to a maximum of 250 lb. The clamps are 0.080"
(just over 1/16") thick plated steel with generously sized handles
for easy operation. The swivel feet have non-marring caps.
Convenient and versatile, these clamps are a great aid to production and jig and fixture work.
(Not compatible with our toggle clamp mounting plates.)
