Petzl Trac Guide Trolley 1 Pack. Featuring an ergonomic captive carabiner it allows staff to quickly install the trolley on the cable with one hand. Because the carabiner pivots the trolley remains in position on the cable when it makes contact with the end brake of the zipline. The ends are equipped with protective impact surfaces to reduce the risk of pinched fingers and two connector support grooves to help avoid abrasion from the cable. The JOKO and AVENTEX lanyards are directly integrated with the carabiner limiting the risk of separation or loss. The carabiner's reinforced construction provides greater resistance to humid and salty environments. Product lifespan is optimized with highly durable bearings and removable impact surfaces available as spare parts.
