CMC ProTech Pulleys
UL Classified to NFPA 1983
The choice for anyone that needs a super light, high strength pulley such as for mountain rescue, ski patrol, tower work, and swiftwater rescue. By machining the sideplates, the thiickness of the metal can be varied to maximize the "strength to weight" ratio, a process that cannot be done with the traditional bent metal sideplates. The unique axle assembly allows a smooth sideplate that will not catch on the surface or other hardware. The aluminum sheave is mounted on sealed ball bearings.
Weight: 3.3 oz
3 sigma MBS: 10,200 lbf (45.5kN)
