Level up your slackline with a 50-meter-long 1-inch webbing with 1 sewn loop. The Viper Slacklines 25mm-wide webbing is suitable for use with a primitive or webbing lock tensioning system to achieve long slacklines. Using a primitive system, it will be possible to setup a length of 35 meters (this tensioning method uses the remaining 15 meters to create the friction wrap). See the Primitive Slackline Instruction Manual for details. To get the full length of your line, use a Boa Constrictor weblock with a slow release. This allows continuous tensioning and opens up longer lengths should you wish to connect additional webbing to your 50-meter line using a soft shackle.
