Irwin Industrial Tool Co 59400CD Handi Clamp 4 Inches

Product Description

The IRWIN INDUSTRIAL TOOL CO 59400CD is a 4-inch variable pressure Handi Clamp designed for one-hand operation in trade and workshop environments. It features C-clamp style jaws fitted with non-marring swivel pads that protect work surfaces during clamping. Clamping force is controlled directly by grip pressure — the harder the user squeezes, the greater the force applied. The clamp locks in position and releases instantly via a quick-release trigger, making it practical for tasks where repositioning is frequent. Electricians, plumbers, HVAC techs, and general tradespeople use it wherever a free second hand is an advantage.

This clamp is suited for light-duty holding tasks on job sites and in shop settings. The 4-inch jaw capacity handles standard workpiece thicknesses common in residential and light commercial trade work. The non-marring swivel pads make it appropriate for use on finished surfaces, conduit, pipe, trim, and other materials where jaw marks are unacceptable. It is sold in a package quantity of 10 units, making it a practical bulk stock item for tool crib replenishment or crew supply.

Compatibility

Designed as a general-purpose one-hand clamp suitable for trade and workshop applications where a 4-inch jaw capacity and non-marring contact are required.

Installation Notes

Inspect swivel pads before each use and confirm they are seated correctly to prevent surface damage. Apply only the grip pressure needed for the task — excessive force beyond what the workpiece requires is unnecessary given the variable-pressure design. Store clamps with the trigger in the open position to reduce spring fatigue over time.
