The WILTON 20487 is a heavy-duty C-clamp from the 400-CS Series, designed for secure workholding in fabrication, welding, and general metalworking applications. It provides a maximum jaw opening of 12 inches and a throat depth of 5.75 inches, giving tradespeople the reach and clamping capacity needed for larger workpieces. The 400-CS Series is built for demanding shop and jobsite use, where consistent clamping force and frame rigidity are essential. Machinists, ironworkers, welders, and maintenance professionals rely on this style of clamp to hold components firmly in place during cutting, welding, drilling, or assembly operations.
The WILTON 20487 is suited for both shop and field use across a range of trades. Its generous jaw opening makes it practical for clamping thick stock, structural steel sections, pipe assemblies, or fabricated parts. It is a standard tool for metal fabrication shops, welding booths, pipefitting operations, and general mechanical maintenance environments where a reliable, full-size C-clamp is required.
Designed as an OEM-style replacement or direct-use C-clamp within the WILTON 400-CS Series product family, compatible with standard workholding setups requiring up to 12 inches of jaw opening.
C-clamps of this size are typically used by welders, fabricators, pipefitters, and ironworkers. Before applying clamping force, ensure the swivel pad is seated flat against the workpiece to prevent slipping or surface damage. Do not use a pipe extension or cheater bar on the handle to exceed the clamp's rated capacity. Inspect the frame and screw threads for cracks or deformation before each use.
