A traditional style, alloy mitre clamp, which holds the joint firmly in position, allowing time for the glue to dry or you can tap in a pin. Countersunk screw holes allow you to secure the clamp onto a board or bench. The saw slot enables you to run a saw blade down through the joint for a perfect fit. These are light-duty clamps designed to do the job well when the occasion arises. The price won't break the bank as you will need to purchase one for each corner of a frame. Timber capacity is 15mm deep by 75mm wide.
