The Unicender by Rock Exotica is an all-in-one ascender/descender that works on both single and doubled rope techniques. This unique device can replace the friction knot in a typical tree climbing system. Invented in 2005 by arborist Morgan Thompson and now produced by world-renowned machining phenomenon Rock Thompson of Rock Exotica.

The Unicender allows smooth frictionless ascent and controlled variable descent on single or double rope but auto locks when released.
