Highest adjustability in the industry with each size having three height positions. 3-step adjusts from 23” to 34” (OSHA compliant at 25.5” and 34”) and 4-step adjusts from 27.5” to 42.5” (OSHA compliant at 34” and 42.5”).
Stair System Components:
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. Also features hardware-free handrails that slide into the platform and lock securely in place with Valco snap buttons. Handrails are universal for left or right installation and fold flat for easy transport and storage. System ships with one riser handrail and one platform handrail.

OSHA compliant and exceeds NIOSH lifting recommendations. Each major component weighs less than 50 lbs. allowing for safe, one-person installation. Welded construction and 6000 series alloy aluminum. Extruded tread for maximum slip-resistance.
Stair System Adjustability and Use:
The platform and riser legs adjust independently allowing for easy, on site leveling. The design also allows the stair system to be easily expanded, reconfigured, or moved.
