21′ Ring Lock Scaffolding Stair Tower

21′ RingLock Stair Tower with Inside Stair Unit

This 21ft RingLock Stair Tower with Internal Stair Unit is a 4-leg vertical access solution designed to lower costs and increase assembly speed. By utilizing integrated internal stair units, this tower provides a secure and efficient way to reach elevated work zones. This tower features a functional landing platform at the top equipped with a safety gate.

The primary advantage of using internal stair units is their one-piece design, which allows them to lock into the tower structure significantly faster than standard modular components. This configuration provides a more cost-effective alternative to traditional RingLock stair systems while maintaining high safety standards. The top landing platform (where your feet are positioned) sits at a height of 21 feet.
