A strong, versatile, and robust pulley system built to last. The SBI Pulleys are a fantastic tool for the cost-conscious slackliner that needs an easy way to get their lines tight. This system comes with everything you need to rig lines up to 100m in length, or any length under 2,000 lbf of tension (8.9 kN).

Built in brake! These pulleys have no need for an external brake system since it's built in to the pulleys! This drastically simplifies the setup and take down of your line and also reduces the amount of gear needed! A super simple tensioning system for all levels of slackliners.

A versatile anchor hole allows for a variety of connectors to attach gear to the pulley system. Soft and steel shackles both work quite well with these pulleys.
