This is a safety chain wrench with a patented chain stopper. Continuous work is possible even in places where a pipe wrench cannot be used, as long as the chain can be inserted. The body is forged from special steel, making it strong, and the teeth are hardened by high-frequency induction hardening, preventing wear and tear and ensuring full functionality. The detachment prevention effect allows for safe and continuous repetitive work. - Applications: Tightening and dismantling work in confined spaces such as gas and water pipes. - Nominal Diameter: (Pipe that can be gripped) 8～75A - Outer Diameter mm: (Pipe that can be gripped) 14～89 - Chain Length: 438mm - Size (Overall Length): 290mm - Weight: 1.1kg Thank you for viewing.
