Compatibility of the first-generation ZIGZAG with CHICANE and KNEE ASCENT
The first-generation ZIGZAG (before 2019) can be used for SRT with the CHICANE auxiliary brake and the KNEE ASCENT access system.
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 SRT mode for accessing and working in the tree
Access and work on single rope (SRT) 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.
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.
Stuck screwgate carabiner
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.
