Wilton GSM50 20 in Bar Clamp 5 1/2 in Throat Depth

Welding and Fabrication Bar Clamp

The Wilton GSM50 bar clamp is built for welding and fabrication tasks that require consistent pressure on workpieces. Its 20 in maximum jaw opening suits a range of material widths, while the 5 1/2 in throat depth provides reach for deeper joints. The tool delivers a clamping force of 2660 lb to hold parts squarely during gluing, joining or machining operations. It is aimed at metalworkers and woodworkers who need a single heavy-duty clamp for large assemblies.

Drop Forged Steel Construction and Sliding T Handle

The bar and handle are both drop forged steel, giving the frame high strength and durability under load. A sliding T-style handle allows quick adjustment and tightening without extra tools, and the swivel jaw pad adapts to angled or irregular workpiece surfaces. This combination means the clamp can be repositioned rapidly and still maintain a secure grip on non-parallel faces during day-to-day shop use.

Check Workpiece Size and Clamping Force Needs

Before ordering, verify that your largest workpiece fits within the 20 in jaw opening and that the 5 1/2 in throat depth reaches the required clamping point. Confirm that 2660 lb of clamping force matches the pressure your application demands; jobs needing significantly higher or lower force may require a different clamp. The tool is not suited for users who need a smaller throat depth for tight spaces or a lighter clamp for delicate materials.
