The Pro Traxion is a high-performance deflection pulley that is especially useful for heavy loads. You can also use it to get your haul bags high up the wall in the bigwall. The high level of efficiency is due to the size of the pulley, which runs on an encapsulated ball bearing. To ensure that the pulley also works perfectly in less favorable conditions, the clamping cam is serrated and has a cleaning slot to provide grip even in mud and ice. The side section is movable to allow the rope to be inserted after the pulley has been installed, preventing the device from accidentally coming off the wall. The Pro Traxion is equipped with a safety lock that can be engaged in the open position to allow the device to be used as a simple pulley. For heavy loads and long bigwalls, a less small device is fine.
