Key AdjustaStairs Features
Self-Leveling Steps
No adjustments, no guesswork. Simply step onto the stair and the tread self-levels underfoot, maintaining a flat, stable walking surface across changing heights and angles.
Lift & Lock Handrails
Raise the handrails into position and lock them in place with a simple wing nut. No tools, no extra hardware. The Lift & Lock design allows handrails to deploy quickly while maintaining rigid, secure fall protection once set.
Easy Anchoring
Bolt the top of the stair to a solid structure such as a slab edge, timber sleeper, or steel frame. At the base, secure the stair using ground pins, bolts, base plates, or clamps depending on the surface to create a stable connection for jobsite access.
How AdjustaStairs Adapts to Height, Angle, and Pitch
AdjustaStairs™ adjusts based on the relationship between stair length, vertical reach, and approach angle. As the pitch changes, each tread automatically compensates to maintain a level walking surface, delivering stable and predictable access across varying heights and site conditions without reconfiguring the stair.
