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.

Magnetic Clamps


Style A	Style B	Style C

Style D	Style E

Hold magnetic workpieces in place.

Style E—Style E clamps have a handle to help pull them off surfaces.

Copper-Plated Steel Body—Copper-plated steel clamps won’t scratch steel surfaces. Their plating also stops weld spatter from sticking to their surface, so sharp spatter won’t cut you or your workpiece.

Easy On/Off Magnetic Clamps


Style A	Style B	Style C

Style D	Style E

Switch the magnets on these clamps on and off for easy placement and removal of your workpiece.

Style E—Style E have magnets on opposite sides that can be turned on and off independently, letting you adjust one workpiece while the other remains clamped in place. They’re commonly used to weld two pieces of metal together.
