Special Use Clamps
Pull-Down Clamp
Single Acting Three capacities available: 870, 3,900 or 6,300 lbs. Use when lateral clamping is desired. Generates straight clamping motion and force along with pull-down clamping force. Pull-down force is approximately 1/3 of the straight clamping force. This clamp is shipped with the jaw shown. The interchangeable jaws can be purchased for use with this clamp. Counter hold devices pull the workpiece down when straight clamping force is applied.
E-11
NOTE: Flexible SAE porting or manifold mounting options. The straight and pull-down movements are independent of each other.
