Wilton 21303 Forged Super-junior C-clamp 1-1/4 in

Product Description

The WILTON 21303 is a forged Super-Junior C-clamp designed for light-duty clamping tasks in trade and workshop environments. With a jaw opening range of 0 to 1.25 inches and a throat depth of 1.25 inches, this compact clamp is suited for securing small workpieces during welding, fabrication, assembly, or fixture work. The forged construction provides greater strength and durability compared to cast alternatives, making it a reliable choice for repeated use. At 0.24 pounds, it is lightweight enough for one-handed placement and repositioning without sacrificing holding integrity.

This clamp is appropriate for use in metal fabrication shops, mechanical assembly lines, HVAC sheet metal work, and general trade applications where a small, strong clamp is needed to hold components in place during fitting or tack welding. Its compact jaw size makes it particularly useful in tight spaces where larger clamps cannot reach. Electricians, pipefitters, and general contractors will find it useful for light holding tasks during installation work.

Key Features

• Forged steel construction for increased strength over cast clamps
• Jaw opening range of 0 to 1.25 inches for small workpiece clamping
• 1.25 inch throat depth for access in confined areas

Compatibility

Designed as a general-purpose small C-clamp suitable for light-duty holding applications across fabrication, assembly, and trade installation tasks.

Installation Notes

C-clamps of this size are typically deployed by hand without specialized tooling. Always ensure the workpiece is fully seated against the clamp anvil before applying load. Do not exceed the rated capacity of the clamp by using a cheater bar or extension on the screw handle. Inspect the forged frame for cracks or deformation before each use, and remove the clamp from service if any damage is found.
