Yale R.I.N.G. Friction Saver

The Yale R.I.N.G. friction saver is a ring-style cambium saver: a length of rope with a ring at each end that sits in the tie-in crotch so your climbing line runs through metal instead of over bark. It is a simple, retrievable setup for doubled-rope climbers.

How a ring friction saver works

Throw a line over the crotch, pull the friction saver up with the small ring leading, and run your climbing line through both rings. The line then bears on the rings instead of the bark, so the tree keeps its cambium and your rope keeps its cover. When the climb is done, a pull on the correct leg brings the small ring back through the large one and the whole thing comes down.

That retrieval step is the part to practice. Rig it wrong and the saver stays in the tree. Set one up at shoulder height and run through it until it is second nature. For other styles, including adjustable and pulley savers, see our friction savers.

Inspection and limits

A friction saver is part of your life-support system. Before each climb, check the rope body for cuts, glazing, and stiff spots, look at the splices or sewn terminations, and check the rings for grooves or burrs. Retire it if it has been shock loaded or shows damage.

Pick a tie-in that is sound and big enough for the load, and keep the rings from levering against the stem. Use it within ANSI Z133 practice and Yale's instructions, and get trained on doubled-rope climbing before relying on it.
