Irwin IR275 Locking C-clamp 24 Inch 12.5 Inch Jaw

Product Description

The IRWIN IR275 is a heavy-duty locking C-clamp designed for gripping, clamping, and holding workpieces securely during fabrication, welding, and mechanical assembly. Built with an alloy steel jaw, this clamp delivers the clamping force needed for demanding trade applications. The standard tip provides a solid, reliable contact point across flat and irregular surfaces. With an overall size of 24 inches and a jaw opening range of 0 to 12.5 inches, the IR275 handles large-scale clamping tasks that smaller clamps cannot accommodate. Ironworkers, pipefitters, welders, and millwrights rely on this type of locking clamp to free up hands and maintain consistent pressure throughout a job.

The IR275 is suited for residential and commercial construction, structural steel fabrication, pipe fitting, and general mechanical work. Its 15.5-inch throat depth allows it to reach deep into a workpiece, making it useful for clamping large sheet goods, structural members, or heavy-gauge assemblies. The locking mechanism holds the set jaw position without constant manual pressure, which is critical when positioning parts for welding or bolting.

Key Features

• Alloy steel jaw construction for durability under high clamping loads
• 24-inch overall size with a 15.5-inch throat depth for deep-reach clamping
• Jaw opening adjusts from 0 to 12.5 inches to fit a wide range of workpiece sizes
• Standard tip provides stable, broad contact on flat surfaces
• Locking mechanism maintains set clamping pressure without continuous hand force

Compatibility

Designed as an OEM-style Vise-Grip locking C-clamp replacement or addition suitable for general fabrication and mechanical assembly applications requiring deep-throat, large-jaw clamping.

Installation Notes

This clamp is installed and adjusted by hand; no power tools are required. Always inspect the jaw and locking mechanism for wear or damage before applying high clamping loads. When used near welding operations, ensure the clamp is positioned clear of arc paths to prevent heat damage to the adjustment screw. Release clamping pressure gradually when removing the clamp from a finished assembly to avoid sudden workpiece movement.
