A two-color cambium saver that protects bark and rope at your tie-in.
The Edelrid Bicolor Cambium Saver is a friction saver that goes around a limb at your tie-in point so your climbing line runs on hardware instead of bark. The two-color design makes the two sides easy to tell apart when you set it from the ground or in the tree.
Climbing a doubled rope straight over a limb grinds the bark, heats the rope and makes every ascent harder. A cambium saver puts rings or hardware between the rope and the limb, so the line runs smoothly and the tree keeps its bark. That matters on prune jobs where the tree stays.
The bicolor design helps when you install and retrieve it: you can see which leg is which and keep the system from twisting. Compare our other friction savers for adjustable and retrievable designs.
Cambium savers also make retrieval tidier. Set correctly, the small ring pulls through the large one when you take the rope down, so the whole saver comes back to the ground with your line. That saves a climb up to collect it at the end of the job.
Choose a sound limb of adequate size, set the saver so the rope runs correctly through it, and follow Edelrid's instructions for use and retrieval. A friction saver is part of your life-support system: it must meet the applicable standard, be used within ANSI Z133 and be installed by a trained climber.
Inspect the sling and rings before every climb for cuts, abrasion, heat glazing and worn grooves. Retire it if the hardware is grooved or the sling is damaged.
