The BSS system is a patent-pending zipline Emergency Arrest Device (EAD)
Barrel Spring System (BSS) is the most innovative compression spring design that the Zipline industry has seen.
These compression springs will reduce the length of your arrival platforms.
Testing is REQUIRED without riders mandatory.
All zip lines are different and will need all non-conservative forces accounted for by a Professional Engineer. Speeds greater that 8 mph with maximum rider weight of 250 pounds will require additional springs and spacers.
Estimates for the number of springs and spacers needed with your first Barrel Spring System purchase can be provided at additional cost.
