10 mm Prusik Grab Lanyard Add-On Kit

This prusik lanyard adjuster kit uses 10 mm hitch cord to turn a plain rope lanyard into an adjustable one. It is a simple, low-cost way to get fine control over your work positioning without buying a mechanical adjuster.

How a prusik lanyard adjuster works

A friction hitch tied with hitch cord grips the lanyard rope when loaded and slides when you tend it. Clip it to your saddle and you can shorten or lengthen your lanyard with one hand while you work. Many climbers still prefer a hitch over a mechanical adjuster because it is light, cheap and easy to inspect.

The 10 mm cord suits common lanyard rope sizes. Check that it is compatible with your lanyard's diameter and cover before you set it up. See more in our lanyard kits section.

An adjustable lanyard is what lets you lean back into a cut at the right distance, then shorten up to move around a limb. Without an adjuster you end up re-tying or wrapping the lanyard, which is slower and easier to get wrong.

Setup and safety

Tie and dress the hitch as you have been trained, and load test it close to the ground before relying on it. Watch for glazing, heat damage and wear on the cord.

This is life-support equipment. Use components that meet the applicable standard, follow the manufacturer's instructions and ANSI Z133, and only climb with gear you have been trained to use.

Keep a spare length of hitch cord in your kit. Cords wear faster than lanyard rope, especially with heavy use, and swapping one out is quick.
