Video - How to install the KNEE ASCENT?

This video presents installing the KNEE ASCENT.

Using a single rope clamp?

A single rope clamp is not trustworthy; it is recommended to use two rope clamps together and/or to use a backup belay system.

Installing the ZIGZAG in SRS mode for accessing and working in the tree

Access and work on single rope (SRS) is a quick and lightweight technique that is adaptable to various work situations. The sequence presented here is one example of many possible variations.

Access on doubled rope with the ZIGZAG

Classic technique that allows the access rope to be left in place, while working in the tree on a second rope. It is suitable for major, long-term projects.

Primary uses of the ZIGZAG

Short down-climb on ascenders

For a short down-climb on a rope, it is not necessarily worthwhile to use a descender. The two ascenders can be moved alternately downward.

A stuck carabiner is a situation that you may encounter, or have already experienced.

How to ensure screws are properly tightened

Many Petzl products are fastened or locked with screws. The tightening torque must be respected and inspected regularly, especially if the device is used intensively.

RAD LINE: small-diameter hyperstatic cord

The cord sold with the RAD SYSTEM was carefully chosen to be suitable for the intended uses, while being compact and lightweight. Its specific qualities limit its application: it is not as versatile as a normal mountaineering rope.
