AdjustaStairs™ Portable Self-Leveling Stair System

Temporary Stair Access That Adapts to Changing Elevations

AdjustaStairs™ are portable, self-leveling aluminum stairs designed for temporary access where site elevations, slopes, and working conditions change. Rather than relying on a fixed-angle stair or ladder, the system adjusts to suit the required vertical height while keeping each tread level for a more consistent walking surface.

Made in the USA, AdjustaStairs™ are used across construction, industrial maintenance, civil, utility, mining, and infrastructure environments where crews need repeatable access into excavations, across changing grades, around trenches, through floor openings, or between temporary work levels.

The system is available in 8- through 20-step configurations, with 24″, 36″, and 48″ widths. Multiple stair units can be connected end to end for longer access routes, while top and intermediate landings can be developed using ProScaf components or custom aluminum fabrication.
