Rock Exotica's Unicender is a highly versatile tree climbing device. It can be attached midline, and is compatible with both single and doubled rope techniques. When ascending, the Unicender has almost no sit-back, ensuring the highest efficiency of movement. The Unicender easily descends as well - simply loop the rope around the plates and control the friction as for most other descending devices. The Unicender is compatible with 11mm to 13mm ropes, and has all the function of a mechanical prussik, with the ability to attach midline, making it a very versatile device.
