Adjustable-length ring saver that fits a wide range of stem sizes.
The KM Tree adjustable friction saver is a ring-and-ring saver with a length you can change, so one saver fits a skinny union and a thick lead. An adjustable friction saver keeps the rings in the right spot instead of riding loose on a small stem or barely reaching around a big one.
A fixed-length saver works well on the stem size it was chosen for. Go smaller and the rings hang far apart, adding drag; go bigger and they may not reach around at all. An adjustable saver lets you snug the rings up on every tie-in, which keeps the rope running smoothly and limits wear on the bark.
Set the length on the ground if you can judge the stem from below, or adjust it at the anchor once you get there. Make sure the adjuster is set and dressed before you weight the system.
An adjustable saver also helps on trees where you plan to move your tie-in during the climb. Instead of carrying two fixed savers in different lengths, one adjustable unit covers the range. Expect it to weigh a little more and take a moment longer to set than a fixed webbing saver.
Check the rope or webbing body, the adjuster and both rings before every climb. Look for glazing, cuts, flat spots and grooves worn into the rings. This is life-support gear. Use it only within the manufacturer's instructions and ANSI Z133 practice, inspect it before every climb, and retire it when in doubt.
Compare it with fixed and webbing models in our friction savers range.
