The Spring Stop adds a little bit of cushion to the end of the ride.  It mounts directly to the cable near the Stop Block. When riders zip down the cable, the trolley bumps into the Spring, which cushions the stops.  The maximum amount of slope is 3% (3 ft. drop per 100 ft. of distance) for zip lines that will utilize a Spring Bumper.

Note:  Riders should have little to no momentum when coming in contact with the Spring Stop.  For riding slopes greater than 3%, we suggest using the Bungee Brake.
