The quick clamp is used for holding workpieces together for drilling, gluing, sawing and fastening.
How to use the clamp:
The quick clamp can be used entirely by one hand. With a few squeezes of the trigger, the bottom clamping jaw moves closer to the top. To release the clamp, push the lever located on the bottom of the handle.
The clamp can be converted into a spreader by undoing the red screw located on the top jaw and repositioning it to the bottom of the quick clamp.
