Polyester 12 Strand has the lowest stretch and highest strength of all polyester constructions. Its torque free braided construction provides easy handling and prevents kinks and hockles. Polyester 12 Strand is delivered standard with a clear polyurethane finish and is easily spliced using a simple lockstitch type splice. The largest market for this rope, transmission stringing lines, typically consists of sets of ropes in four different colors.
