Medium-Duty One-Handed Bar Clamp evenly distributes up to 300 lbs. of sustained clamping force; equipped with removable, non-marring pads and a removable swivel jaw, the Medium-Duty One-Handed Bar Clamp can tightly hold even the most irregular of shapes. It is constructed of an I-beam bar to reduce flexing and bowing, and it has a classic pistol grip design and Quick-Releaseâ„¢ trigger for one-handed operation. With a simple push of the Quick-Changeâ„¢ button, this clamp easily converts into a spreader or a specialty clamp with the installation of one of the One-Handed Bar Clamp Accessories.
