Rothenberger 70245 llave de cadena para tubos n.º 6, capacidad 6 pulgadas / 168 mm, cadena de 600 mm, acero forjado, mordazas reversibles de doble cara, recubierta en polvo

On a construction site or in a plumbing workshop, when a pipe fitting is seized and a standard wrench slips, the Rothenberger 70245 chain pipe wrench takes hold. Its 600 mm chain wraps around the pipe, and the self-clamping mechanism locks on as you apply force, so you can break loose or tighten even rusted or polished pipes up to 6 inches (168 mm) in diameter. The double-sided, reversible jaw means you can flip it for longer life, and the induction-hardened teeth bite into the surface without slipping. The forged steel body and powder-coated finish stand up to daily professional use, while the ergonomic handle reduces strain during repetitive tasks. This is the tool for plumbers, pipefitters, and maintenance crews who need a reliable, heavy-duty grip on large pipes and fittings.
