Piher's Maxipress F-Style Piston Clamps feature dual-threaded screw mechanisms that multiply both clamping speed and force. The threads are split into upper and lower sections, both of which are completely encased in a metal cylinder: the ''piston.'' The two screws are threaded opposite one another, and work together to close the clamp 50% faster than ordinary clamps. They also generate 40% more force—up to an incredible 2,025 pounds. In addition, the clamp foot advances like a piston—without spinning—so any twisting forces that could cause misalignment or marring are minimized.
Clamp foot advances without rotating, minimizing any twisting torque that could cause misalignment or marring
Totally enclosed threads keep out weld spatter, dust, glue and protects the threads from impact or arc strikes
Grease port allows you to lubricate the screw threads when necessary
Handle swivels 90° in either direction and locks into place for additional leverage. Use it in the in-line position where space is restricted
Grooved jaw heads let you clamp tubular items and other profiles
Spring-assisted brake prevents the movable jaw from sliding open, even without clamping force
Heavy-duty cold rolled steel bar provides incredible beam strength and maximum durability
