The Patent Pending Magnapulleys offer a revolution in equipment flexibility, providing a Double Sheave Pulley that splits apart into two Single Sheave Pulleys, drastically reducing the hardware necessary for work and rescue rope systems. This flexibility is a great advantage to small teams who have to travel or climb a great distance to their work site (Mountain Rescue, Military/Tactical, Work at Height, Arborist, Etc.) and need to strip down their kit to the minimum. Held together by four ultra strong Neodymium Magnets embedded in the back plate, the Magnapulleys make a clean set of Double Pulleys. When split apart for use as Single Pulleys, the magnetic characteristic provides the added advantage of attracting to metal, a benefit for hands free manipulation on antenna towers, maritime access missions, etc.
