How does the zip line bungee brake work?
What it is: The zip line bungee brake consists of a block on the cable that resembles a small brick but is free to slide up and down. A bungee cord is connected between the block and anchor point (usually a tree or post) off to the side of the zip line.
How it works: When the rider comes zipping down the cable, the pulley will make contact with the block, pushing it down the line; this in turn stretches the bungee cord, providing resistance. The brake slows the rider to a gentle stop near the end of the cable. For better explanation check out our video on it: Bungee Brake Installation
