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 a 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!

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.
