- 24kN High Breaking Strength allows the Prusik loop to expand its areas from professional to general uses. CNC machine stitching of sewn joints keeps the loop neat and free from traditional bulky knots, whilst still withstanding high strengths; A heavy transparent heat shrink sleeve is applied around the stitching to protect it from abrading during use and allow you to easily inspect the stitching condition. That has the Prusik loop gain unbeatable durability and longer service life.

How to choose Prusik diameter?
- In most cases, the Prusik cord should be about 60% to 80% of the standing line (main rope) in diameter.
- Skinnier cords will have a too-tight bite, Thicker cords in opposite can't generate enough grip on the standing line and tends to slip.
- For safety, always take tests of the Prusik knot to slide and re-grab on the rope in safe places prior to using it at height.
