Wide Opening-Automatically Adjusting

Open Arm, Flanged Base

Automatically adjusts for different workpiece thicknesses. Clamps with the same, repeatable force anywhere within its 1-1/4" automatic-adjustment range. Ideal for welding fixtures, machining fixtures for castings, fixtures holding several part sizes within the same family, or any other application where part size can vary. Fits in the same space, and provides the same clamping force as the same-size standard toggle clamp. Arm opens 106° while handle moves 58°.Open arm provides adjustable spindle location. 750 lbs. holding capacity.

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.
