The Rothenberger 36 in. Heavy Duty Pipe Wrench is built for maximum strength, durability and gripping power on the toughest large-diameter pipework. A cast iron housing and precision-machined, full-floating forged jaws deliver superior gripping force and long-lasting performance under extreme jobsite conditions. The I-beam handle design reduces weight without compromising strength for better balance and control, while a spring-loaded jaw ensures secure engagement on every turn and a knurled adjustment nut allows quick, easy positioning even with gloved hands. For plumbers, mechanical contractors and industrial maintenance crews, the 36 in. wrench delivers power, reliability and results that stand up to the job. Material: Steel.
