Perfectly sized for model-making, crafts, small projects and tight spaces, the TEKTON Mini Ratchet Bar Clamp / Spreader applies precise, consistent pressure to hold work pieces together for gluing or assembly. Press the quick-release button to freely position the jaw, then squeeze the trigger to apply pressure. Once set, the jaw is locked and will not creep. Soft jaw pads offer sure grip, but will not damage surfaces. When the job is finished, simply press the quick release button to let go of the work piece. If you need to push pieces apart or press them against outside surfaces, convert the clamp to spreader by loosening wingnut and moving fixed jaw to the opposite end of bar. Material: Composite.
