Irwin Industrial Tool Co 19 Locking C-clamp 11 Inches

Product Description

The IRWIN INDUSTRIAL TOOL CO 19 is an 11-inch locking C-clamp with regular tips, designed for gripping, clamping, and holding workpieces securely during fabrication, welding, plumbing, and general mechanical work. The regular tip profile provides broad, stable contact across flat and slightly curved surfaces. At 8.45 pounds, the clamp is built with substantial mass that supports heavy-duty holding force in demanding trade environments. This tool is a staple for pipefitters, welders, plumbers, and HVAC technicians who need reliable one-handed clamping with consistent jaw pressure.

This locking C-clamp is suited for both residential and commercial job sites. It is commonly used to hold pipe sections, structural components, sheet metal, and framing members in position during fitting, welding, or fastening operations. The 11-inch jaw capacity allows it to span larger workpieces than standard mid-size clamps, making it a practical choice for heavier fabrication tasks. Each package contains 5 units, which supports crew-level stocking for contractors and service shops.

Key Features

• 11-inch jaw opening accommodates larger workpieces and structural members
• Regular tips provide broad, stable contact on flat and mildly curved surfaces
• Locking mechanism holds clamping pressure without continuous hand force
• Substantial 8.45-pound construction supports heavy-duty clamping loads

Compatibility

Designed as a general-purpose locking C-clamp for use across fabrication, mechanical, plumbing, HVAC, and welding applications where an 11-inch jaw capacity is required.

Installation Notes

This clamp is installed and removed by hand using the adjustment screw and release lever — no special tools are required. Always ensure the workpiece is stable and supported before applying full clamping force. Do not use the clamp as a structural support or lifting device. Inspect the jaw mechanism and screw threads before each use to confirm smooth, consistent operation.
