    "Troy's passive braking trolleys and barrel spring systems are excellent for any zip line. I witnessed that their trolleys could stop 275 lbs. and 35 lbs. consistently (using the same pin placement for the slope) at the bottom. These braking products will reduce your risks and your zipline's liability!"

Most operation manuals are huge (up to 150 pages) and filled with technical jargon that's impossible to understand.

Our manuals are short and easy to read with interactive videos and links to the standards.
