The IRWIN INDUSTRIAL TOOL CO 225103ZR is a 3-inch C-clamp designed for secure workholding in trade and industrial applications. The double-rolled thread increases clamping speed, allowing faster setup without sacrificing holding strength. A large swivel pad distributes clamping force evenly, reducing marring on finished or delicate work surfaces. The oversized handle delivers greater clamping pressure with less hand effort, reducing fatigue during repetitive clamping tasks. This clamp is sold in a package quantity of 5, making it well suited for shops and job sites that require multiple clamps on hand.
The 225103ZR fits into everyday workflows for electricians, plumbers, pipefitters, carpenters, and general contractors. It is appropriate for light fabrication, positioning pipe and conduit during layout, holding components during soldering or brazing, and securing workpieces to benches or fixtures. The 3-inch throat depth handles a wide range of common material thicknesses encountered in residential and commercial trade work.
Designed as a general-purpose C-clamp suitable for use across trades including electrical, plumbing, pipefitting, and light fabrication applications requiring a 3-inch jaw capacity.
No dedicated trade license is required to use a C-clamp, but proper clamping technique applies across all trades. Always ensure the swivel pad is fully seated against the work surface before applying final clamping pressure. Do not use a pipe or extension on the handle to exceed the tool's designed clamping force, as this can damage the thread or the workpiece. Inspect the thread and swivel pad before each use and remove any debris that could cause uneven clamping.
