A roller friction saver from ART that protects bark and rope at the tie-in.
The ART Ropeguide Twinline is a roller friction saver that sets at the tie-in and lets your climbing rope run over rollers instead of grinding across bark. It protects the cambium, keeps rope wear down and makes advancing your system smoother.
Climbing directly over a branch wears the bark and your rope, and adds friction that makes advancing harder. A friction saver like the ART Ropeguide puts hardware between the rope and the tree. Rollers keep the rope running freely, so you spend energy climbing, not fighting friction.
ART is known for engineered climbing gear, and the Ropeguide line is built for the way climbers actually set and retrieve tie-ins.
The Twinline layout also helps when advancing or adjusting a tie-in. With the rope running over rollers, it slides through easily, so you spend less effort taking up slack and less time fighting friction at the top of the climb.
Set it on a sound, appropriately sized anchor and follow ART's instructions for configuration and retrieval. Inspect the rollers for free movement, check the sling and hardware for wear, and keep it clean. Life-support gear has to meet the applicable standard and the manufacturer's instructions, get inspected before every climb, and be used only by trained climbers.
Compare it with simpler options in friction savers.
Clean the rollers after sappy jobs. Pitch and grit stop them turning freely and add friction back into the system. If a roller sticks, wobbles or shows wear, stop using it until it has been fixed or replaced.
