These heavy-duty clamps are designed for high-demand professional and industrial use. The steel I-bar is extremely strong and resistant to twisting and bending. The sliding head is cast of tough ductile iron and features a 4-piece, hardened steel clutch.
The Jorgensen 48-Inch Heavy-Duty Steel I-Bar Clamp is made with extra carbon and manganese to hold up to industrial use. It features a multiple-disc clutch with automatic gripping for a secure hold that is easily released. The clamp opens up to 3 feet, with a 2 by 1 3/4-inch clamping face and 5/8-inch cold-drawn steel screw for added gripping power. The crank-type handle is simple to operate, and Jorgensen backs its clamp with a 1-year limited warranty.
