Rock Exotica Omni 4.5



The Rock Exotica Omni-Block 4.5 Material Handling Pulley (MHP58) is the largest pulley in the Omni family, featuring a large 4.5-inch sheave and 2.7 tonnes WLL. The 4.5 is the first Omni-Block to accept up to 19mm rigging lines. The integrated swivel allows the block to orient while reducing gain during lifting and rigging applications. The rope can be installed and removed with one hand, all while remaining connected to the anchor — precision-manufactured in the USA by Rock Exotica. This rigging block is massive!
