The Petzl PRO TRAXION is a super-efficient progress capture pulley. Its large diameter sheave with sealed ball bearings make it particularly useful for hauling heavy loads over longer distances. It was designed so that you can install your rope while the pulley is connected to an anchor. The side plate locks in place when loaded to prevent the pulley from opening during use. The progress capturing cam may be locked in the open position for use as a simple pulley.
Designed for 8mm to 13mm rope
