ClimbingPro grade

The KM-III Max adjustable friction saver is a retrievable tie-in that you can size to the limb, so one saver fits a wide range of crotches and stems. It protects the bark and your climbing line while giving you a clean, low-friction anchor.

Why adjustable

A fixed-length friction saver works only within a narrow range of limb sizes. Too short and it will not wrap; too long and the rings sit badly. An adjustable saver lets you set the length to the limb you choose, so you can tie in where the tree gives you the best anchor rather than where the saver happens to fit.

The Max version is meant for climbers working bigger trees who need extra reach. Compare our other friction savers to see fixed and ring-to-ring styles.

Setting and inspecting

Install it only as the maker's instructions describe, and make sure the adjuster is set and locked before you weight it. Choose a sound limb and avoid sharp crotches that can pinch the sling. A friction saver is life-support gear: it must meet the applicable standard, be used within ANSI Z133 and be installed by a trained climber.

Before every climb, check the sling for cuts and abrasion, the adjuster for wear and correct function, and the rings for grooves. Retire any part that looks damaged.

Practice installing and retrieving it on a low limb before you rely on it high in the canopy. Adjustable savers have more steps than a fixed sling, and you want to know the sequence well before you are doing it from the ground on a tall tree with the crew waiting.
