Pulley with optimal durability for acrobatic routes at height TRAC GUIDE is a pulley designed for acrobatic routes at height. Equipped with an ergonomic and captive carabiner, it allows the supervisor to quickly install the pulley with one hand on the cable. Thanks to the pivoting of the carabiner, the pulley is held on the cable when it comes into contact with the end brake of the zip line. The ends are equipped with stops to limit finger jamming and two supports for connectors, preventing wear by friction on the cable. The JOKO and AVENTEX lanyards are integrated directly onto the carabiner to make the assembly captive. The reinforced construction of the carabiner gives it better resistance to humid and saline environments. The lifespan is optimized, thanks to the bearings with optimal durability and the carabiner and removable stops and available as spare parts.
