Build your zip line braking system with this 1/2" heavy duty bungee cord.
- Choose the "by the foot" option to choose a custom length.
- Choose the 15' length for any mild to moderate zip line less than 200' in length.
- Choose the 30' length for steep zip lines and zip lines between 200 and 500 feet in length.
This heavy duty 1/2" bungee is intended to be stretched up to 175% of its orginal length. For example a 20' length of cord can safely be stretched up to 35'. Stretching the bungee more than 175% of its original length will greatly reduce its useful life and increase the possibility for bungee failure.
