The CMC CSR2 Double Pulley is a high-strength confined space and technical rescue pulley engineered for raising, lowering, and hauling operations involving life safety rope. Classified to both NFPA General Use and EN 12278 standards, the CSR2 combines exceptional strength, efficient performance, and innovative load-handling capabilities in a lightweight, rescue-ready design.
Designed to accommodate 11 mm to 13 mm life safety rope, the CSR2 utilizes CMC’s patented locking system that eliminates the need for a toothed cam or Prusik. This allows the pulley system to be released safely and easily while under load, even when fully collapsed. An integral thrust-bearing swivel automatically aligns the pulley with the load, reducing torque and increasing both efficiency and operational safety. Machined from a solid block of aircraft-grade aluminum, the CSR2 delivers outstanding durability while maintaining a lightweight profile suitable for demanding rescue and industrial applications.
