High-Access AdjustaStairs™ System

High-Access Stair Systems for Changing Jobsites

AdjustaStairs High-Access provides a practical stair-based access solution for elevated, temporary, and changing work areas. Available in 22- to 40-step models, the system is designed for projects where crews need repeatable vertical access beyond the range of standard portable stairs.

Each model adjusts within its specified height range, while the self-leveling tread system helps maintain a consistent walking surface as the stair angle changes. This makes AdjustaStairs well suited to construction phases, excavation work, maintenance activities, and other applications where access conditions are not fixed.

Built from heavy-duty marine-grade aluminum, High-Access AdjustaStairs combines elevated reach with a portable, fold-flat design for transportation and storage between work areas.
