These patented barrel springs reduce initial impact by stopping the rider more gradually than traditional springs.

Determining how many springs you will need is easy! Simply take the incoming speed of your rider and for each mph, you need that many springs. (e.g., a 20-MPH zipline needs 20 springs for a 230-lb zipliner). 

All spring systems REQUIRE TESTING to the maximum anticipated speed and load as per ACCT. Can be completed with a minimum of 250 lb. weights, sandbags, or bagged rock salt.

These Zipline  Brakes install in minutes, NOT hours.

Made in the USA.

Each spring array includes a bumper at the beginning for trolley strikes.
