The largest, most efficient block from Rock Exotica, features a large 4.5" sheave and 6,000 lb WLL. Designed with 3,000 lb Capstan Hoists in mind, the block can handle up to 3/4" rope. The block is designed for material handling and features red side plates to easily differentiate it from other Rock Exotica Omni Blocks which aren't designed for overhead lifting.
