4-Inch Carriage C-Clamp

The Wilton 540A-4 is a 4-inch carriage C-clamp built for regular-duty clamping tasks. Its cast iron body with black oxide finish provides durability, while the powder coat adds corrosion resistance. A steel spindle with a swivel pad ensures even pressure distribution across the workpiece.

Woodworkers and metalworkers needing deep reach

This clamp suits users who require a 2-1/16 inch throat depth to reach past flanges or edges. The 2,150 lb clamping pressure handles moderate assembly and glue-up jobs. Buyers needing wider jaw openings or higher pressure ratings for heavy structural work should consider other options.

4-inch maximum opening capacity

The clamp opens from 0 to 4 inches, defining the thickest material it can secure. This single measurement determines whether the tool fits the specific workpiece dimensions in your project. Verify your maximum material thickness against this figure before purchase.
