Overview

An aluminum corner clamp weighing 3.45 pounds, built to hold two workpieces square at a right angle while glue sets or fasteners go in.

Corner clamps solve a specific problem, keeping a picture frame corner, a box joint or a cabinet edge square while the joint is worked on. Aluminum keeps the tool lighter than a steel equivalent, which matters when it is held in one hand while the other drives a screw. It only handles right-angle joints, not flat panel clamping.

Material: aluminum
Item weight: 3.45 pounds
Joint type: right angle corner
Category: clamps

Who it's for

Good for woodworkers and DIYers assembling frames, boxes or cabinet corners. Not a fit for clamping large flat panels or angles other than 90 degrees.
