AdjustaStairs™ | Articulating Stair System
SafeSmart's patented AdjustaStairs™ system is a purpose-build solution designed to replace job-made ladders, extension ladders, and even traditional switchback stair towers. With rapid setup, industry-leading strength, and fully adjustable functionality, AdjustaStairs™ delivers compliant and reliable access in a fraction of the time. Perfect for accessing trenches, decks, mezzanines, or multi-slab construction, the AdjustaStairs™ system is engineered to meet the toughest job conditions, while keeping crews safe and productive for years to come.

Fast Deployment - No Delays
Install in Under 10 Minutes
AdjustaStairs installs in minutes, not hours. With a pre-assembled, fold-flat design, two people can deploy the stair in under 10 minutes—no complex setup, no site-built components, and no wasted time getting crews up and moving safely.
Self-Leveling Treads
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.
Simplified 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—creating a stable, fixed connection that meets OSHA requirements.
How It Works
How AdjustaStairs Adapts to Any Height, Angle, or 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, predictable access across varying heights and site conditions without reconfiguring the stair.
