Rock Exotica Unicender Mechanical Ascender & Descender RG50

Since its inception in 2005, the Unicender has been the most flexible tool for tree climbing. With the ability to be used in both Doubled Rope Technique (DdRT) and Single Rope Technique (SRT), the Unicender fits the way you like to climb like no other tool. The Unicender utilizes unique friction plates that allow it to advance easily with minimal friction, and virtually no “Sit Back,” giving you the most efficiency per stride. Descending is just as easy: by looping the rope around the plates in SRT. Additionally, the Unicender attaches conveniently mid-line. For rope sizes 11 to 13mm, or 7/16” to 1/2”. Note: A new Unicender slips on the rope at 1200 lbs, and less as it wears. This is a safety feature for the tool and the user. When exposed to a shock load such as a fall, the Unicender slips before it breaks. This slip also limits the shock to the user. The Unicender is not a fall arrest tool, and should be retired after a hard fall. The Unicender climbing tools ultimate breaking strength is 7,000 lbs. That is 2,000 lbs more than the industry standard.
