Rock Exotica has a long history of producing innovative pulleys. In the late 80’s, in collaboration with Arnor Larson, we developed the original knot-passing pulley. Later we developed the Omni-Block, with the integrated swivel and locking sideplate. Today, the Mini Machined pulley and Machined Rescue Pulley offer uncharacteristically high strength for their small size and weight. All our pulleys reflect Rock Exotica’s uncompromising standards for design, materials and manufacturing.
