    Our braking system design improved with friction braking trolleys. We also utilize their Barrel/Telescoping springs which have provided an Emergency Brake that stands alone, with no participant resetting requirement.

  • Ken Moore (Robertson Harness)

    "Troy's Friction Braking Trolleys and barrel spring systems are excellent for any zip line. I witnessed that their trolleys could stop 275 lbs. and 35 lbs. in the same location, using the pin placement designed for the zipline's slope. Their braking products will reduce your risks and your zipline's braking risk!"
