Wet-Environment Flexible Rope—Not for Lifting

Made of polypropylene, this rope floats in water, resists rot, and doesn’t lose strength when wet. It also resists acid, oil, and gas. This rope has a braided cover with a strand core, so it bends freely. You can peel back the cover and remove the core strands to use it in light duty tying applications. This rope will not rotate under load.

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

Wet-Environment No-Flatten Rope—Not for Lifting

This polypropylene rope floats in water, resists rot, and doesn’t lose strength when wet. It also resists acid, oil, and gas. Solid braided construction keeps the rope from flattening during use and disperses wear evenly, making it a good choice for high-friction applications, such as passing through pulleys. It knots easily and does not rotate under load.

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

UV-Resistant Wet-Environment Grip-Tight Rope—Not for Lifting

Also known as truck tie-down rope, this rope has added UV-ray inhibitors to protect it from deterioration when used outdoors. Rope is polypropylene so it floats in water, resists rot, and doesn’t lose strength when wet. It also resists acid, oil, and gas. The twisted construction gives rope a grooved surface, allowing you to grip it tight without it slipping.

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