Very useful for holding a workpiece that is to be glued. The cursor moves easily with the yellow handle and to tighten simply use the big stick and attached greenhouse holds well. You can also reposition the tip to be used towards the outside which is handy if you want to keep in place the elements on either side of a door jamb for example. We use it to build a wooden house and we bought other greenhouses attached, I confirm the high quality of this product which for the moment is the only one held in reliability robustness and efficiency. So good I recommended
