Bahco Chain Strap Wrench

The Bahco 370-4 Chain Strap Wrench is a heavy-duty tool designed for tightening large diameter pipes and tubes in confined areas. With a maximum capacity of 110mm (4 inches), this professional-grade wrench delivers a high-strength, positive grip that enables secure fastening without requiring chain removal between operations.

Built for demanding plumbing and pipefitting applications, this chain wrench features a specialised jaw design that allows bi-directional operation, making it ideal for both tightening and loosening tasks. The 300mm tool length provides excellent leverage whilst remaining manageable in restricted spaces where conventional wrenches cannot operate effectively.

The serrated jaws are induction hardened for long-lasting performance, ensuring consistent grip and durability even under heavy use on commercial and industrial projects. This makes the wrench particularly suitable for plumbers, heating engineers and maintenance contractors working with large bore pipework, drainage systems and industrial tubing installations.
