IRWIN Quick-Grip 12-Inch One-Handed Bar Clamp, Heavy-Duty, 600 lb

Powerful, one-handed clamping for woodworking

The IRWIN Quick-Grip 12-Inch One-Handed Bar Clamp, Heavy-Duty, delivers up to 600 pounds of sustained clamping force. Its rugged I-beam bar resists bending, keeping components aligned under pressure for demanding tasks like installation, rough glue-ups, and cabinetry work.

Dual swivel jaws with non-marring full-face pads distribute clamping pressure evenly across the surface. If you need to work with irregular shapes, the pads detach to allow the jaws to swivel and maintain full contact every time.

Versatile design for real-world workflows

A Quick-Change button makes it simple to switch from clamp to spreader, saving time when you need to reposition parts without removing the clamp. An adjustable foot lets the clamp stand upright on a bench, freeing your hands for alignment and glue-up steps.

Designed with a pistol-grip handle and a smooth Quick-Release trigger, this clamp emphasizes one-handed control while delivering robust clamping power. The combination of power, versatility, and stability helps you approach projects with confidence rather than strain.

Getting the most from your clamp

Store with jaws closed to keep alignment accurate. Use the upright stand for gluing large panels, and switch to spreader mode for separation or quick repositioning tasks.
