Rolley - 25mm Slackline Roller

Roll along webbing and make the magic of mechanical advantage possible. By arranging your Rolley as a pulley using a Grippex in a buckingham system you get an ideal mechanical advantage of 3:1. In reality, this means you can tension your slackline as if you had an extra pair of hands helping. When setting up a longer slackline and adding tension using mechanical advantage, we recommend using a slow release in your system to safely loosen the line after. Specifications: Minimum breaking strength: 25kN
