20 in. Heavy Duty F-Clamp - (GSM50)

Steel construction delivers this clamp, opening 0 to 20 in. with 2,660 lbs. of clamping force and a 5-1/2 in. throat depth. Built for demanding fabrication, construction, and production environments, the heavy-duty steel bar handles sustained high-pressure clamping without deflection. The oversized sliding jaw mechanism provides a wide bearing surface that prevents bar scoring and maintains smooth slide action over extended service life. A comfort-engineered handle delivers full clamping force without the hand fatigue that comes from repeated high-force tightening throughout a work shift. Hardened contact pads grip workpieces firmly while distributing pressure to prevent surface indentation on metal plate and structural members. The GSM Heavy Duty series is the professional fabricator's choice when F-clamp force ratings measured in thousands of pounds are not negotiable.
