SAN FRANCISCO The explanation is simple. The SSR materials provide the highest resist-ance to abrasion and prevent fusing on bitts. The JETKORE construction wherein each strand contains a core of untwisted polypropylene, which is compressed by a unique, patented process into a homogenous mass of strong fibers, imparts as much as 15% greater strength to the rope. All this at no additional weight and therefore no additional cost. JETKORE construction also provides greater resistance to distortion, kinking and hockling. SSR is manufactured in two types . . . SSR-100 and SSR-200. Each strand of SSR-100 contains a single outer layer of yarns, each of which is composed of a polyester jacket over polyethylene. SSR-200 has two such layers of combination yarns. JETKORE construction (Pat. No. 3,380,243) will now be furnished for all SSR, PNX, PNX-Type T and polypropylene ropes in the following sizes: 3 Strand ? 6" circumference and larger 8 Strand Square Braided ? 7" and larger Remember, no one but AMERICAN can offer you the patented JETKORE construction.
