Note
- Rope Stopper is the most common equipment used to temporarily share the load of the main line rope when it is tied to a bit.
- Covered Polyester offers superior abrasion resistance and increasing coefficient of friction.
- Core UHMWPE offers high strength and minimum elongation under load, providing excellent control and stability.
- Very lightweight enables easy to handle and work.

Guide to Inspection
With fibre ropes, the stopper used should ideally be of the same material as the rope being stoppered, with synthetic stoppers for synthetic lines and natural fibre stoppers for natural fibre lines.
The MBL of the stopper should be around 50% of the MBL of the line being stoppered. Polyamide (nylon) stoppers should not be used on polyamide lines due to the low coefficient of friction of the material. (Safe Mooring Practice, 2009)

5. Additional Requirements
The MBL of the stopper should be around 50% of the MBL of the line being stopped. Polyamide (nylon) stoppers should not be used on polyamide lines due to the low coefficient of friction of the material.
