Corner Clamp

Clamps that hold two pieces square — or at 45° — while glue goes off or a weld is tacked. The standard clamp covers picture frames, boxes and light joinery; the heavy-duty casting takes larger section without flexing; the mitre version is shaped for a 45° joint rather than a square corner.

• Check before ordering: Check the jaw capacity against your material thickness — a corner clamp that will not open far enough is no use at all.
