These stainless steel blocks are the latest in a long list of great pulley designs by CMI. Engineered to take on the most demanding rigging jobs, the block cheeks are made from high strength stainless steel to give you years of service. Aluminum alloy bushings and sheaves are supported by zinc plated steel axles. Upper bushing is easily accessed by a no-slip nob, and it is captive, so you won't loose it. Sheave is 4" in diameter and is supported by a sintered bronze bushing. Cheek plates are broad enough to protect lines during use and polished to a shine. Blocks have a manufacturer work load limit (WLL) of 6,000 lbs at 7:1 ratio and weigh approximately 5.6 lbs (2.5kg).
