The JET Speed Bar Clamps come equipped with the exclusive ergonomic SUMOGRIP® handle. Unlike wooden handles, the SUMOGRIP® delivers a softer, stronger grip for added comfort and increased torque. The user can also count on easy turning with the effortless Acme Thread that ensures smoothness without any binding. The JET Speed Bar Clamp assortment is available in both 3” and 5” throat depths. The 5” deep throat Speed Clamp provides increased versatility during any assembly project. The Precision-Rule® provides consistent setup and quick identification of opening capacity. The non-marring pads on the clamping surface eliminate damage to the workpiece.
