Fits in the same space, and provides the same clamping force as the same-size standard toggle clamp.

Setup and Operation
Easy to use. To set up initially, first adjust the contact spindle so that the arm is in the middle of its adjustment range at average workpiece height. Next, set desired clamping force once, by turning the adjustment screw with a screwdriver. Approximately 250 lbs. clamping force is the most that can be applied by hand, at the farthest spindle location. After that, operate just like a standard toggle clamp-the patented adjusting mechanism does the rest.
