The RP283 Rope Wrench has been optimized to achieve best friction performance on 13mm (1/2") ropes. The RP283 Rope Wrench allows the climber to ascend and work the tree in a stationary rope system on their favorite hitch.

The rope daimeter range of the original Rope Wrench covers 11-13mm ropes, but ISC received feedback that the Rope Wrench encountered additional friction at 13mm. The new RP283 Rope Wrench has been designed to provide optimal friction on these larger ropes, to ensure the smooth performance climbers have come to expect.

The RP283 Rope Wrench can be easily told apart from the original by the black sheave on the RP283. This model is wider to accomodate a wider sheave groove for 13mm (1/2") ropes.

Advantages of the Rope Wrench

The SRT Advantage: Climbing SRT has many advantages. It allows the climber to ascend at a 1:1 rate of speed. For every foot they pull on the rope they ascend one foot. This is different from the conventional DdRT (double rope technique) configuration of 2:1. In DdRT the climber must pull two feet of rope to advance one foot.

The Wrench Advantage: Using a Rope Wrench has advantages over many other SRT systems as well. Climbing with mechanical ascenders allows one to rapidly ascend the rope but the climber must perform a changeover to descend. The Rope Wrench dissipates friction and heat away from the climbers friction hitch allowing the climber to descend.

The Rope Wrench is essentially a descent device that has a neutral gear that allows it to ascend the rope as well. Because of this neutral gear, it is imperative that the Rope Wrench be used with a sturdy and trusted friction hitch.

Configuring the Rope Wrench

There are many ways to configure the Rope Wrench properly, but the climber must be secured to both hitch and Rope Wrench. Any hitch that works safely in DdRT should work with a Rope Wrench. The Rope Wrench is the "limb that goes with you". It provides the same service to your climbing hitch that the tree limb or cambium saver provides in DdRT

Friction Adjustment: The ZK-1 allows the tree climber to adjust the amount of friction they prefer by sliding the bottom friction bolt up or down before locking it into place. The ability to adjust the friction is very important as it allows a climber to fine tune the Wrench to their climbing line and hitch combination.

Tether Selection: The tether of the rope wrench should be installed in a manner that gives the friction hitch enough room to function properly but short enough to not be sloppy in the climbers system.

RP283 Rope Wrench for Use by Trained Climbers

The RP283 Rope Wrench is recommended for tree climbers who have a working knowledge of Single Rope Technique. This means you have received qualified training and have practical experience climbing SRT.
