Product Information

Pitbull Clamps

The Pitbull Clamp is a revolutionary new fixture clamp with positive force and a low gripping profile. High vertical and horizontal clamping forces are generated, considering the size of the Pitbull Clamps. It uses a standard cap screw and an oil resistant O-ring. The Pitbull Clamp is available in 5 sizes and several styles. A tool steel knife edge for aggressive stock removal, a tool steel blunt edge for general purpose and a brass version to help prevent marring the work piece.

Pitbull is a registered trademark of the Pitbull Clamp Co, Inc.
