PETZL Belay & Rappel Equipment Editorial Review

The Petzl Basic Ascender Decender is a premium brand small ascender that is designed to work with 8mm to 11mm rope. It is rated for a weight of 140kg/308lbs but cannot be used to hang people. This device is used on nylon rope, not metal cable, and it should not be used to hang any live load. The Petzl Basic Ascender Decender is rope-friendly with sharp teeth that do not shred the rope. It is easy to use and attaches to the rope simply, even with one hand. However, it is a bit bulky and heavy. Customer feedback has been largely positive, with users praising its quality and functionality. It is a great addition to a ropewalker or for canyoning and mast ascension systems. It is also very easy to install and use. One user did report that the product did not work on the rope size advertised and was unhappy, but this was an isolated incident.
