Every Zip Line needs some sort of braking system. These Zipline Brake Systems are often called passive braking and active braking. In active braking, it is up to the rider that has to initiate the braking using usually a leather glove. This type of zipline braking can be very dangerous method because the rider must reach up and grab the cable to slow down.
The opposite and what we highly recommend is called Passive Braking involves no physical effort by the rider. This is a much safer option for families and children backyard zipline riders.
