The "Boa constrictor" is our strong and lightweight weblock that easily pre-tensions. It is perfect for use in high tension slacklines and highlines. The integrated slow release system lets you safely detension the line and a captured pin ensures it won't be left behind.
After 4 years of research, testing, and development we are proud to present the Viper Slackline "Boa constrictor" weblock. Light-weight, strong, and easy to pre-tension!
The Boa weblock integrates perfectly with our slow release, holding the tension of your slackline or highline using friction. When setting up longer lines, higher tensions are best achieved using a combination of our Grippex and Rolley to setup the Buckingham 3:1 tensioning system.
