Petzl MAESTRO® S Descender 10.5mm - 11.5mm

MAESTRO S is a descender designed for technical rescue operations. It facilitates manipulation of heavy loads, for lowering or hauling, and may be used in both the primary system or in a back-up belay.

• Color: Yellow
• Rope Compatibility: 10.5mm - 11.5mm
• Materials: Aluminum, Stainless Steel, Nylon
• Sheave type: Faceted, on sealed ball bearings
• Maximum working load: 550 lbs (250 kg)
• Breaking Strength: 36 kN (7000 lbs)
• Efficiency: 86%
• Certifications: CE EN 12841 Type C, EN 341, NFPA 2500 Technical Use, EAC
• 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 back-up belay
  • lower connection point can be used to create different types of hauling systems
  • hole in the handle for installation of a distance control cord
• Easy to use:
  • easy rope installation, thanks to the markings on the device
  • ergonomic handle allows the rope to be released progressively and enables comfortable control of the descent
  • immediate shift from lowering position to hauling position 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 to adjust the friction based on the load and the rope diameter
  • handling of loads up to 250 kg
