These are smaller versions of the low-profile horizontal and in-line Bessey auto-adjust toggle clamps (our items #17F72.01 and #17F72.03).
They automatically accommodate material thickness changes (up to 13/16" for the horizontal clamps, 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 or a perpendicular base that lets you mount the clamp on the edge of a clamping surface.
The flat-mount and perpendicular-mount horizontal clamps have capacities of 1-3/16" and 1-7/16" stock thickness respectively. Both in-line clamps have an 11/16" throw; the flat-mount 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". 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.
