Irwin Quick-Grip has added parallel jaw clamps to its line up of clamping tools. With parallel jaws and a 3-3/4" throat depth, the jaw clamp provides a precise 90 degree angle and delivers powerful clamping force of up to 1,150 lbs. A secure locking system prevents the jaws from slipping off the work piece by maintaining a consistent clamping force throughout the task. In addition, the resin body and jaws prevent marring the work piece and resist glue adhering to the clamping surface.
