Rock Exotica UNICENDER. This revolutionary device combines ascending and descending in one piece of gear. Works with both single and double rope technique, with seamless transition between ascending and descending.

The UNICENDER is a versatile rope climbing tool that features:

– Ascending and descending with both doubled rope technique (DdRT) and single

rope technique (SRT).

– To descend, the top and bottom handles are squeezed together. There are two

ways to do this (in both DdRT and SRT). :

1.CONTROL MODE. The rope is wrapped around the handles and used

to release by squeezing them together. This is the safest method because

you are holding the rope under tension and this makes it harder to lose

control.

2. ADVANCED MODE. You can release by squeezing the

handles together with your hand. But it will release more suddenly and if

you panic you will continue holding it and will fall uncontrolled, causing

injury/death. You should not use this mode unless absolutely necessary.

We recommend that you never use this mode; we are including the

information about it because users will quickly discover it and we want

them to know it is extra dangerous.

When descending you must always control the free side of the rope with your

hand just as you would when using a figure 8 or other rappel device. DO NOT

depend on controlling your descent only with the UNICENDER.

– Auto advance in DdRT: When ascending using doubled rope technique you

simply pull the rope exiting the UNICENDER it will automatically advance ahead

of you.
