Frequently Asked Questions

1. How should I wash my rope?

Keeping your rope clean is critical to its longevity. Sterling Rope recommends using Wicked Good Rope WashTM, our proprietary wash, free of any harmful chemicals that might breakdown the fibers in your rope. Wash your rope after approximately 30 to 40 uses, or if the rope has excessive dirt throughout the sheath. Your rope can be washed by hand, or in a washing machine, preferably a front-load washing machine, using hot water. Sterling does not recommend a top-loading washing machine because the rope can become entangled in the agitator and this could harm both the rope and the machine. If you are using a tub or container, make sure it is clear of any chemicals that could be harmful to the fibers in the rope. Hang your rope to dry in an area not exposed to sun.

2. What is a Marathon sheath?

A Marathon Sheath is a Sterling Innovation. This sheath uses heavier denier nylon than any other dynamic rope on the market. We do this to enhance the rope's durability and longevity.

3. What is DryCore?

DryCore is our unique nylon core construction that reduces yarn on yarn abrasion of wet nylon fibers, helping to maintain the original strength and elongation characteristics of your ropes. Only Sterling ropes have DryCore. Please note that DryCore does not guarantee you rope will stay dry, but that when the rope is wet the fibers will maintain more of their strength and stretch.

4. What's the difference between a BiPattern and BiColor?

BiPattern ropes are a pattern shift in the middle of the rope. Neither the color nor yarns change. BiColors are produced by changing the yarns to a completely different color yarn at the middle of the rope by using an air splice technique.

5. When should I retire my rope?

There are certain rules to follow when deciding when to retire your rope. It is important to inspect the rope before and after each use. This inspection should be both visual and physical by running your hand over the entire length of the rope. If the rope has any sheath degradation, where the core is visible or coming through, or if it is punctured or glazed, it is time to replace the rope. Often times the ends of a rope wear faster if loaded, due to tying and knotting. If this is the case, it may be possible to cut off the damaged section of the rope and continue using the rest.

Even with the closest inspections and impeccable usage, the fibers in rope break down over time. Because of this we have basic retirement guidelines. Ropes should be retired from service after five years of use or ten years after the manufacture date. Reference your care instructions for further information and if you are in doubt about the condition, age or previous usage of a rope; it is always better to retire it.


6. Why does my BiColor rope have fuzzy bumpy yarns at the middle mark?

Those fuzzy bumpy spots are Air Splices. An air splice is the joining of two yarn ends by means of high-pressure air forced around the ends causing them to entwine and snarl together. Air splices are essential to join strands into usable lengths. From a life safety perspective two yarns air spliced together test out to be 50% stronger than continuous straight fibers because they have twice as much yarn in the section that is air spliced.
