CMC ProSeries CSR Pulley > Locking Swivel Pulley Confined Space Rescue Pulley
UL Classified to NFPA 1983 - General Use
Patent Pending Completely redesigned and refined for 2006, the CMC CSR Pulley (#300337) is a professional tool for Confined Space Rescue and numerous other rope access and rescue applications. It has a proprietary locking system and unlike other pulleys that rely on a toothed cam, the CMC CSR Pulley can be unlocked while under load. By eliminating the cam, the pulley system is much more compact when fully collapsed. Another safety feature is the integral swivel that reduces torque by aligning the pulley with the load. A built-in swivel is considerably more compact as it eliminates the need for multiple connections to incorporate a separate swivel, robbing the raising system of valuable clearance under tripods. The forged steel eye provides exceptional strength. The CSR Pulley, and its companion Swivel Double Pulley (#300336), both have high strength aluminum side plates, sealed ball bearings, and anodized aluminum sheaves. Accepts 7/16 and 1/2 in. (11 to 13 mm) diameter rope. Benefits • Easy to lock and unlock for better control, even under a load • Built in swivel eliminates need for multiple connections and prevents twisting. • More compact size saves valuable clearance space under tripods.
