The Robertson Large Zip Tour Pulley represents the most advanced design work using state of the art engineering techniques to build the safest and finest trolley for the ropes course industry.

• 304 stainless steel frame is .101 thick for superior strength and trouble free use
• Assembled using machined 304 stainless axles which give unparalleled structural integrity
• Uses two additional back-up bolts for safety that also provide superior stability
• Sheaves are 2" in diameter, case hardened to 56-58 Rockwell, and ride on sealed ball bearings to provide excellent wear characteristics in challenging outdoor environments
• Built for 3/8" and 1/2" diameter cable
• Long hang down plates keep the users hands away from the cable while allowing the user to maintain body alignment with the cable
• Handles are not meant to be hung from, but are meant to keep the user facing forward on the ride
• Optional hook-in points allow various positioning of the riders, making this pulley the ultimate for adventure parks
