CMI Friction Saver with Aluminum Rings

The CMI friction saver with aluminum rings is a classic ring-and-ring design that keeps your climbing line off the bark at the tie-in point. Aluminum rings keep it light on the saddle and in the throw-line setup.

How a ring-and-ring saver works

One ring is larger than the other. Set the saver over a limb with a throw line, pass your climbing line through both rings, and the rope runs smoothly on metal instead of bark. When you finish, a retrieval line lets the small ring pass through the large one so the saver comes down to the ground.

It is a simple, proven setup for MRS climbing, especially on pruning work.

Ring-and-ring savers are popular because they are simple and easy to retrieve. Set it on a sound union high in the tree with a throw line, then install your climbing line from the ground. When the job is finished, retrieve it carefully so the rings do not hit anyone working below.

Aluminum ring care

Aluminum wears faster than steel, so check the rings for grooves and sharp edges before every climb. Inspect the connecting strap or rope too. Retire the saver if the rings show deep wear or the strap is damaged.

Keep the retrieval line separate and clearly marked so it is never mistaken for your climbing line. Check that the saver has fully cleared the union before you pull it down, and call out before it falls.
