Nylon Windlass Rope – Cornerstone 8
For the Marine IndustryCornerstone 8 Anchor Line ropes are manufactured with a rope designed to work with all windlass on the market (consult the owner’s manual for the correct size.) Cornerstone 8 is non-rotational thus eliminating hockling and other problems associated with twisted anchor lines. With Cornerstone 8 spliced directly onto the chain, the assembly easily enters and exits the windlass.
* Consult your windlass owner’s manual for the proper size.
- We recommend using ¼” chain with the ½” windlass and 5/16” chain with the 5/8” and ¾” windlass.
- 8-strand windlass rope stretches and absorbs shock loads to protect your boat, is comfortable to hold and has good abrasion resistance for durability and value.
- 8-strand windlass rope flakes and falls on to itself more compactly than 3 strand rope in the locker (will not bird nest) allowing more to be stored in the same space.
- Pre-soak 8-strand rope for two hours before first use. Do NOT use dry and new.
- Customization for length, eye size and private logo packaging is available.
- Working load: 20 – 25%
Applications: Anchor lines
Industries served: Marine
Uses: Windlass applications

Rope Safety Considerations
New Rope Tensile Strengths: New rope tensile strengths are based on tests in accordance with ASTM Test Method D-4268 on new and unused rope in laboratory condition.
Working Loads: Working loads are for rope in good condition with approximate splices, in non-critical applications, under normal service conditions. Working loads should be exceeded only with expert knowledge of conditions and professional estimates of risk. Working loads should be reduced where life, limb, or valuable property is involved, or for exceptional service conditions such as shock loads, sustained loads, etc.
The Cordage Institute specifies that the Safe Working Load of rope shall be determined by dividing the Minimum Tensile Strength by the Safety Factor. Safety factors range from 5 to 12 for non-critical uses.
