In the single rope technique (SRT), the Unicender takes the place of both ascenders and descender, preventing the climber from having to switch out hardware with every change in direction and thereby enabling SRT to be a viable working system and not just a canopy entry method.

When descending, the Unicender can be used in either the “squeeze-to-go” configuration like a friction hitch or the “squeeze-to-stop” configuration like a figure 8, which makes it customizable according to each climber’s individual panic response. This incredible new device works by snaking the rope through the 'jaws' where smooth wear surfaces apply friction to the line.

The Unicender can be used with either 11mm or 12mm diameter line (up to 13 mm) without changing any parts, can be easily installed mid-line, and can be sent back to the factory to be rebuilt when the wear surfaces are worn out. Climbers using the Unicender consider this the best climbing hardware they have ever invested in!
