To eliminate the need for frequent adjustment, these toggle clamps from Bessey are designed to automatically accommodate material thickness changes of up to 1" without altering the clamping force.
The high-profile and low-profile horizontal clamps have capacities of 2 3/4" and 2" thick respectively and the vertical clamp has a 1 9/16" capacity; the in-line clamp has a center height of 7/8" and a 1" throw. Each has a knurled screw to adjust the clamping force to a maximum of 550 lb. The clamps are 0.100" (just over 3/32") thick plated steel with generously sized handles for easy operation. The swivel feet have non-marring caps. Convenient and versatile, these clamps expedite production and jig and fixture work.
These toggle clamps are also available with mounting plates.
