The Ideal 31-839 is a 1/4" x 250 Pro-Pull rope. This rope is yellow with a blue tracer, the low friction polypropylene rope slides easily through conduit as well as not splintering so it can be handled without gloves. This rope will not stretch, rot or mildew. With a tensile strength of 3780lbs this rope is great for almost any job. In 1916, J. Walter Becker started the Ideal Commutate Dresser Company of Chicago from his mothers kitchen. He manufactured commutate dresser stones with the belief that every product should be worth more than the price paid for it. Service, he said, was part of the product. That idea has been the core IDEAL business principle for over 90 years. Today, the many loyal distributors and customers that make IDEAL successful are a testament to Beckers original philosophy.
