Available Options



Easy-to-install 96” canopy for overhead protection from the elements. The rust-resistant Canopy features an aluminum frame with 22-gauge galvanized steel roof. Attaches directly to the FORTRESS Stair, which means no footings or building alterations are needed.


Features a sturdy, boxed-frame design for superior strength and durability and all fittings are made of high quality aluminum or galvanized steel. The four-post canopy has cross member supports for wind load resistance.

Simple Installation

One-person assembly in under 30 minutes.

Safety and Durability

Exceeds NIOSH lifting recommendations. Each major component weighs less than 50 lbs. allowing for safe, one-person installation.

Adjustability and Use

The rapid-swap design also allows the canopy to be easily moved as needed. Generous, 96" measurement from walking surface to roof ensures plenty of door swing and light fixture clearance.

Oversized Feet

May eliminate the need for pavers in most soil conditions.

Platform with Drain Holes

Helps facilitate drainage with additional .75” holes in platform surface.

Secondary Handrails

If handrails need to be installed on both sides, additional riser handrails and platform handrails are available.

  • Can you connect two Stair Systems together to create an up and over?

    Yes, we do have this capability; however, you cannot connect two standard models together without a few extra parts and pieces. This particular configuration would be a custom stair system requiring additional hardware and handrails. Ask us about this configuration and how we can help get you the right solution for your project – we have lots of capabilities with this product.

  • Do you offer a side approach and front approach?

    Yes, we offer both. The side approach is a standard offering and the front approach is a very simple custom stair system with a minor handrail reconfiguration. Ask us about this type of configuration!

  • Can the stair be connected to a building?

    Yes, we recommend attaching the stair to the building using pre-drilled anchoring holes, which are on all sides of the stair system’s platform.

  • Are the stairs adjustable?

    Yes, both sizes of our OSHA Stair System are adjustable. The FOR2334 is adjustable to heights between 23” and 34” and the FOR2742 is adjustable to heights between 27.5” and 42.5”. The legs are adjustable and each size has two riser settings/positions; one with the top riser flush with the platform and one with the top riser one riser height below the platform. Use our FORTRESS Calculator to help!

  • At what heights are the stairs OSHA compliant?

    The FOR2334 is OSHA compliant at 25.5” and 34” and the FOR2742 is OSHA compliant at 34” and 42.5”.

  • Are the stairs easy to transport?

    Yes, the handrails fold flat and can also be used on either side for versatility. The stairs are also made of lightweight aluminum.

  • What kind of surface is used?

    Our tread consists of extruded aluminum with raised ribs for permanent slip resistance.

  • Do you offer a canopy for the stairs?

    Yes, we have a canopy option for our OSHA stair.

  • How many handrails are included?

    One handrail is included and can be used on either the left or right side of the stair system based on your needed configuration.
