Nylon Double Braid
Manufactured by Miami Cordage, our Nylon Double Braid is an exceptional rope for various applications that require high strength and substantial shock absorbing properties. The nylon fibers have high elongation and stretch properties, making this type of rope ideal for shock loading applications such as anchor, mooring, towing and dock lines. Torque-balanced construction prevents hockling, while special tension setting and stabilization processes keep the rope dimensionally stable.
Features
- Excels in strength, abrasion resistance and flexibility
- Predictable and controlled elongation
- Excellent shock absorption
- Torque-balanced construction
- Custom designs & colors
- Military Spec: MIL-R-24050
- Mooring, anchor, towing and dock lines
- Pendants, shock absorbers and decoration

Compliance to the above specifications is based upon testing according to the Cordage Institute Standard Testing Methods for Fiber Rope and/or ASTM D-4268 Standard Methods of Testing Fiber Ropes.
Weights:
are average and may vary +/- 5%.
Tensile strengths:
Are approximate average for new, unused ropes. To estimate the minimum tensile strength of a new rope, reduce the approximate average by 15% (Cordage Institute defines minimum tensile strength as two standard deviations below the average tensile strength of the rope).
Nylon ropes value of strength is self-evident, but the benefits of elasticity may not be as obvious. When your boat surges against an unyielding dockline, the load on the line goes from zero to the maximum at the instant the nylon line comes taut. The likely consequence is a broken line-not unlike how you might snap a piece of thread with a jerk. Even if the nylon rope is strong enough not to break, it is hammering cleats and bitts with every surge. Nylon rope doesn't come taut suddenly, but dissipates the load by stretching. It is like the difference between hitting the steering wheel or hitting the air bag.
As for nylon rope's resistance to ultraviolet damage, docklines, particularly permanent docklines, live in the sun. Nylon lines enjoy a much longer life than other lines in that environment.
