Tool-Free Setup - Height Adjustable - Safer Access in Minutes
FASTER, SAFER ACCESS WHEREVER YOU NEED IT
THE LIGHTWEIGHT, SELF-ADJUSTING
STAIR SYSTEM REPLACING LADDERS NATIONWIDE
AdjustaStairs is revolutionizing how crews access heights on construction and industrial sites across the country. This patented, OSHA-compliant stair system replaces ladders—one of the leading causes of jobsite injuries—with a safer, faster, and far more reliable solution. In under five minutes, two people can install AdjustaStairs with no tools, no specialist knowledge, and no need for complex scaffolding or additional certification. Once secured at the top and bottom, and the handrails are raised, it’s ready for immediate use.
Each unit features self-leveling treads that automatically adjust to suit a wide range of angles and elevations, creating a consistent and stable walking surface on uneven terrain, between decks, or down into excavations. Built from lightweight yet heavy-duty marine-grade aluminum, AdjustaStairs is easy to reposition and durable enough for long-term use in the harshest environments. No matter the job, AdjustaStairs helps companies eliminate unsafe ladders, reduce fall risks, and dramatically improve productivity.

ONE DESIGN WITH VAST APPLICATIONS
FLOOR-TO-FLOOR ACCESS
Moving between slabs or decks in commercial builds often means relying on ladders or temporary scaffold stair towers—both of which create safety concerns and slow down workflows. AdjustaStairs provides fast, reusable floor-to-floor access that installs in minutes and self-levels to match slab elevations. The available 48” wide version supports higher foot traffic and better crew flow in busy areas, reducing congestion and improving safety. If you’re searching for temporary stairs between levels, construction slab-to-slab access, or a ladder replacement for multi-story sites, AdjustaStairs is the tool of choice for modern builds.
SLOPE ACCESS
Navigating slopes and embankments on construction sites often requires makeshift solutions or dangerous ladder use—neither of which offer the safety or stability crews need. AdjustaStairs is engineered to self-level on angled terrain, creating a reliable stairway across batter slopes without scaffolding or custom fabrication. Crews can easily join multiple units end-to-end to span long runs, and secure them using simple ground pinning and sleeper fixes. If you’re searching for safe slope access stairs, temporary stairs for uneven ground, or construction site batter stairways, AdjustaStairs delivers unmatched safety and speed—eliminating the hazards of unstable access routes.
EXTENDED HEIGHT ACCESS
When access is needed across elevations of 20 feet or more, scaffold towers become time-consuming, costly, and risky to erect. AdjustaStairs solves this with a modular extended-height model that reaches up to 32 feet with the addition of a bolt-on truss—engineered to safely support up to 1,100 lbs. Designed for fast deployment, it eliminates the need for large labor teams or complex setup while maintaining full OSHA compliance. If you’re looking for high-reach construction stairs, scaffold stair tower alternatives, or modular stairs for multi-level access, AdjustaStairs delivers unmatched performance and simplicity.
MID-LANDING OPTIONS
Rail corridors, electrified platforms, and multi-level sites often require safe mid-landings for continuous stair runs. However, these environments also introduce restrictions around drilling, electrical safety, and rapid setup. AdjustaStairs solves this with fiberglass stair options for non-conductive safety and mid-landing kits that clamp securely into place—no structural penetration needed. Ideal for rail maintenance access stairs, modular mid-landing systems, and temporary access between platforms, AdjustaStairs ensures safe movement without delays or compliance issues.
TRUCK ACCESS
Accessing truck trays safely is a common challenge across job sites, logistics yards, and maintenance depots. Traditional ladders are unsafe, unstable, and non-compliant with many jobsite safety protocols. AdjustaStairs was specifically developed for truck tray height access—with self-leveling treads that adapt to tray heights between 3’3” and 4’11”. No fixings or tools are required, making it ideal for fast, secure loading and unloading. If you’re looking for OSHA-compliant truck stairs or a portable alternative to ladders for flatbeds, AdjustaStairs is the durable, reusable solution trusted across industries.
CUSTOM ACCESS
No two worksites are the same, and access requirements can vary widely based on layout, industry standards, and compliance regulations. AdjustaStairs offers full customizability to meet unique access needs—whether you’re bridging complex entry points, connecting to existing structures, or complying with pedestrian access regulations or IBC stair code requirements. AdjustaStairs can be configured for long-term or temporary use, indoors or out, across construction, infrastructure, and industrial environments. For teams searching for custom temporary stairs, compliant jobsite stair access, or adjustable worksite egress solutions, this system is built to adapt without compromise.
