Petzl Maestro S Rescue Descenders

Petzl Maestro S Rescue Descenders

Designed for technical rescue operations, the Petzl Maestro S Rescue Descenders is a high-performance descender that streamlines the handling of heavy loads.

Whether used in a primary system or as a backup belay, its versatile design adapts to a wide range of rescue scenarios.

Featuring an ergonomic handle and integrated brake, the MAESTRO S offers precise and comfortable control during descent. Transitioning from lowering to hauling is fast and seamless—no need to transfer the load. The integrated progress-capture pulley, equipped with a large diameter sheave on sealed ball bearings, ensures exceptional hauling efficiency.

The AUTO-LOCK system automatically secures the rope when the handle is released and allows rope take-up without additional handling.

Compatible with 10.5 to 11.5 mm ropes, the MAESTRO S supports loads up to 250 kg, making it an essential tool for professional rescuers.

Features:

• Great versatility, ideal for technical rescue:
  - The locking system with integrated progress-capture pulley allows the same device to be used for lowering 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 installing a remote control cord
• Easy to use:
  - Markings on the device make rope installation easy
  - Ergonomic handle allows the rope to be released progressively and enables comfortable control of the descent
  - Changing from lowering to hauling is immediate, without the need to transfer the load
  - The 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
  - Faceted sheave creates additional friction zones for the rope and provides additional braking when lowering
  - Integrated brake on the device to adjust the friction based on the load and the rope diameter
• Compatible with 10.5 to 11.5 mm ropes for handling loads up to 250 kg Other Usage Characteristics:
  - Can be used with a 10 mm rope for a working load limit up to 150 kg
  - Can handle loads up to 272 kg when used with an 11 mm NFPA-certified General Use rope
