Product Features 

  • Stair System Components

    The Fortress® OSHA Stair System platform legs feature captured fasteners allowing for a wide range of adjustability. The one-step riser connection uses an OSHA safety pin to lock the riser to the platform. The Fortress also features hardware-free handrails that slide into the platform and lock securely in place with Valco snap buttons. Handrails also fold flat for easy transport and storage.
  • Safety and Durability

    The Fortress® OSHA Stair System is OSHA compliant, and exceeds NIOSH lifting recommendations. Each major component weighs less than 50 lbs. allowing for safe, one-person installation. With welded construction and 6000 series alloy aluminum, the Fortress OSHA Stair System is designed to withstand the rigors of everyday use.
  • Stair System Adjustability and Use

    The Fortress® OSHA Stair System, with its quick adjustability fits most applications. The platform and riser legs adjust independently allowing for easy leveling on the job site. The design also allows the stair system to be easily expanded, reconfigured, or moved.
