After years of design cooperation with the US Navy, Phillystran co-engineered the PSFS 4 strand aramid (Kevlar® / Twaron® / Technora®) fiber ropes with sequential break technology which reduces the rope’s recoil if overloaded to the point of break (See Cordage Institute standard CI 1502 for effective lengths). This is an important safety feature which is mandated on many US Navy vessels. These ropes have been specifically designed for mooring lines, head lines, breast lines, or any application requiring ropes that are tough, light, easy to handle and splice – with safety in mind. PSFS ropes consist of four aramid fiber strands around an independent synthetic core. Each strand is individually jacketed with alternating aramid and polyester yarns for excellent abrasion. The rope is built in accordance with MIL-SPEC A-A-50435B. Standard reel lengths are 600 feet. Weights and dimensions can vary.
