The Groz Duo Bar Clamps, are unique clamps with both external and internal clamping options. These are manufactured from drawn steel with a section of 1-1/4" x 1/4" (32 mm x 6 mm), Equally spaced holes along the entire length allow for clamping of a vast range of sizes. The robust malleable iron head and slide can be easily reversed on the bar allowing for both internal and external clamping.

A spring-loaded pin allows the head and slide to be adjusted at any desired position on the bar, making it highly customizable. The internal clamping feature is especially useful for holding window or door frames in position or holding partitioning in place during construction. Our clamps have a throat depth of 2.1/8" (55 mm) and clamp face width of 1.3/16" (30 mm), making them the perfect tool for any job that requires precision and flexibility.
