"Master L" product description
Petzl brand Maestro L descender designed for technical rescue operations. It facilitates the handling of heavy loads, both lowering and lifting, and can be used in a main system or in a safety system at the same time. This versatility allows rescuers to adapt to all the configurations that can be found at the scene of the intervention.
The ergonomic handle and integrated brake allow comfortable control of the descent. The passage from the lowering position to the hoisting position is immediate, without having to return to the load. The integrated blocking pulley, with a 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 grip. It is compatible with ropes from 12.5 to 13 mm and allows handling loads of up to 280 kg.
