The BESSEY GSV300M Double Force All-Steel Variable Bar Clamp Set is a modular clamping system designed for large-scale steel fabrications, custom assembly jigs, and extra-wide workpiece joining. Built with an impressive 118 in. clamping capacity and a 5-1/2 in. throat depth, this system utilizes a heavy-duty 1-3/16 x 5/8 in. (30 x 15 mm) steel rail profile to deliver up to 2,000 lbs. of clamping force across extreme spans.

Engineered for ultimate versatility, the GSV300M features tool-less removable rail end slide stops that allow fabricators to reverse the sliding arms for spreading applications or add extra sliding arms to secure multiple workpiece sections simultaneously. The sliding arms are fitted with drop-forged steel components, heat-treated ACME threaded spindles resistant to weld spatter, and heavy-duty MorPads that tilt up to 35 degrees to accommodate angled or uneven workpiece surfaces.
