Petzl Master S descender designed for technical rescue operations. It facilitates the handling of heavy loads, both in descent and in lifting, and can be used in both a main and a safety system. This versatility allows rescuers to adapt to all the configurations that may be found at the site of the intervention. The ergonomic handle and integrated brake allow you to comfortably control the descent. The transition from the lowering position to the lifting position is immediate, without having to resume the load. The integrated locking pulley, with large diameter faceted sheave and the sealed ball bearing, ensure excellent lifting performance. The Auto-Lock system automatically locks the rope when the handle is not in use. Once locked, rope can be retrieved without having to manipulate the handle. The Maestro S descender is compatible with ropes from 10.5 to 11.5 mm and allows the handling of loads of up to 250 kg. Characteristics:
