Shock-Absorbing Easy-Splice Rope—Not for Lifting

Made from nylon, this rope compensates for sudden force, such as in towing applications and dock lines. A polyurethane coating gives this rope wear resistance for high-friction applications. It’s braided with a hollow core, so it’s easier to splice than other rope when adding a fitting or connecting rope together. It doesn’t rotate under load.

Note: The safety factor for capacity is 12:1.

Shock-Absorbing Wear-Resistant Rope—Not for Lifting

A braided nylon core protected by a braided cover makes this rope resistant to both wear and sudden forces, such as those found in towing applications and dock lines. The braided construction also prevents the rope from rotating under load. When wet, this rope can lose up to 20% of its strength. It resists rot.

Nylon-covered rope resists mildew.

Polyester-covered rope resists UV rays, oil, and gas.

Polyurethane-coated rope is good for high-friction applications since its coating gives it increased wear resistance.

Rope with Eye on Both Ends—Not for Lifting

Rope has an eye on both ends to save time when attaching to tie downs and hooks. It knots easily and won’t rotate under load. Polyethylene rope is strong even when wet. Its performance is comparable to Spectra and Dyneema. It’s commonly used as a lightweight alternative to wire rope because of its excellent strength to weight ratio.

Note: The safety factor for capacity is 12:1.
