Product Description

The WILTON 20307 is a heavy-duty C-clamp from the 400 Series, designed for gripping, holding, and securing workpieces during fabrication, welding, and general metalworking operations. It offers a jaw opening range of 0 to 12 inches and a throat depth of 5.75 inches, giving tradespeople and fabricators the reach needed to clamp thick stock or deep assemblies. The 400 Series line is built for industrial and professional use, making this clamp a standard tool in metal shops, construction sites, and maintenance environments where reliable holding force is required.

This C-clamp is suited for applications in structural steel fabrication, pipe fitting, welding setups, and general mechanical assembly. The 12-inch jaw opening accommodates a wide range of material thicknesses, while the 5.75-inch throat depth provides access to workpieces that extend well back from the material edge. It is typically used by ironworkers, pipefitters, welders, and maintenance mechanics who need a dependable clamp for both production and field work.

Installation Notes

C-clamps of this size are typically handled by fabricators, ironworkers, pipefitters, and welders. Ensure the swivel pad is properly seated on the workpiece before applying full clamping force to avoid slippage or surface damage. Inspect the screw thread and swivel pad for wear before each use. Do not use a cheater bar or extension on the handle to exceed the clamp's rated capacity.
