Corner Clamps

Clamp two workpieces at 90° to make corner joints. These clamps are often used in woodworking, framing, and assembly projects. The clamping surfaces are nylon to protect finished or delicate workpieces from marring. Mounting holes allow you to permanently attach these clamps to a workbench for repeatable setups.
