Description
Petzl Maestro S Descender
The Maestro S is a descender designed for technical rescue operations. It makes it easier to manipulate heavy loads when lowering or hauling and can be used in both the primary system or in a backup belay. This versatility allows rescuers to adapt to a variety of different situations they may encounter on the rescue scene. The ergonomic handle and integrated brake enable a comfortably controlled descent. Changing from lowering to hauling is immediate, without the need to transfer the load. The integrated progress-capture pulley has a large diameter sheave mounted on sealed ball bearings, providing excellent hauling efficiency. The AUTO-LOCK system automatically locks the rope when the handle is not in use. Once locked, the rope can be taken up without having to manipulate the handle. The Maestro S descender is compatible with 10.5 to 11.5 mm ropes and can handle loads up to 250 kg.
