This CRL Quick-Grip® Bar Clamp/Spreader only takes one hand to operate and has a quick release trigger for fast positioning of the jaws. Jaw throat depth is 3-1/4" (83 mm). Large non-marring vinyl jaw pads offer maximum glass or finish protection and gripping strength. It converts into a spreader quickly with no tools required. The multi-position jaw can be positioned anywhere on the bar making even the most challenging clamping or spreading task a snap. One finger unlocks a quick-release trigger that releases in a snap. Made of high tech resin so it is light and easy-to-handle.
