These clamps have twice the capacity of standard C-clamps.

With five times the capacity of standard C-clamps, these are the highest capacity clamps we offer. They tighten with a wrench.

The jaws move in unison to apply even pressure and prevent twisting. These clamps have grooved clamping surfaces that are good for holding round material. They also known as cantilever clamps.

A bright finish makes these clamps easy to see.

The clamp body is extra-slim to fit into narrow openings.

Press the quick-release button and slide the screw into position to make adjustments in less time. Turn the screw for final tightening.

Lighter weight than other metal clamps, these are less likely to bend thin material.

Three screws apply pressure to three sides of a workpiece.

Plastic clamping surfaces prevent damage to material.

Made entirely of fiberglass, these clamps won’t transmit electricity and are chemical resistant. They're often used around electrical equipment as well as in plating and anodizing applications.

Plastic clamping surfaces prevent damage to material. The jaws on these clamps move in unison to apply even pressure and prevent twisting. They are also known as cantilever clamps.

Clamp the side of a workpiece as well as the top and bottom. These clamps have jaws that move in unison to apply even pressure and prevent twisting. The grooved clamping surfaces are good for holding round material. Copper plating on the clamping surfaces and screw resists weld spatter. They are also known as cantilever clamps.

All components of these clamps are made of aluminum-bronze that is FM approved. They satisfy OSHA requirements that specify nonsparking tools for locations where flammable vapors and combustible residues are present.

Warning: Do not use these tools in direct contact with acetylene.
