Descender with integrated progress-capture pulley for loads up to 280 kg, compatible with 12.5 to 13 mm ropes
 
MAESTRO L is a descender designed for technical rescue operations. It makes it easier to manipulate heavy loads when lowering or hauling, and may 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 L descender is compatible with 12.5 to 13 mm ropes and can handle loads up to 280 kg.
 
Description
Great versatility, ideal for technical rescue: 
- Locking system with integrated progress-capture pulley allows the same device to be used for descent and hauling 
- Can be used in both a single or twin primary system and in a backup belay (more information on this technique in the Instructions for Use and technical tips at www.petzl.com)
- Lower connection point can be used to create different types of haul systems 
- Hole in the handle for installation of a remote control cord 
Easy to use:
- Markings on the device make it easy to install a rope 
- Ergonomic handle allows the rope to be released progressively and enables comfortable control of the descent 
- Immediately changes from lowering to hauling without having to transfer the load 
- AUTO-LOCK system allows the rope to be blocked automatically when the handle is not in use; once locked, the rope can be taken up without having to manipulate the handle 
Efficient for handling heavy loads:
- Integrated progress-capture pulley with very large diameter sheave mounted on sealed ball bearings; rotates in only one direction for excellent hauling efficiency
- Sheave is faceted, creating additional friction zones for the rope and thus additional braking on descents
- Integrated brake on the device adjusts friction based on the load and rope diameter 
- Can handle loads up to 280 kg 
Rope compatibility: 12.5 to 13 mm diameter
