Get a sure grip on round or irregularly-shaped pieces while cutting, fastening, assembling, riveting, or welding with the TEKTON Locking Chain Clamp. This unique and versatile tool does what other clamps can't, holding things like smooth-surfaced round pipes, rebar and threaded rods, and almost any other shape you can find. Wrap the chain around workpiece, hook through nearest link, then squeeze handle to lock. When finished, unlock with the one-touch quick release lever. It operates easily, even with gloves on. A chrome plated finish protects from rust and corrosion.
