Rock Exotica Unicender Ascending and Descending Device

The Unicender by Rock Exotica is an all-in-one ascender/descender that works in both single and doubled rope techniques (SRT and DdRT). This unique “mechanical split-tail” design replaces the friction element (tied hitch) of a DdRT tree climbing system. This mechanical device works well with many climbing lines and provides a solid work positioning device that can quickly be switched over from MRS to SRS. The T6 alloy Unicender also functions cleanly on single line for work positioning and is not limited to use by professionals only— recreational or beginning climbers will find it a rewarding investment for occasional to regular use as well. For rope sizes 11 to 13mm, or 7/16 to 1/2 inches.
