The Irwin quick-grip one-handed bar clamp, medium-duty, provides up to 300 lbs of sustained clamping force evenly distributed across removable swivel jaws.
It is constructed with an i-beam bar to reduce flexing and bowing, non-marring pads that protect workpieces and can be removed quickly, and a unique pistol grip design with a quick-release trigger for one-handed operation.
This clamp easily converts to a spreader with a few simple turns of the quick-change button.
