The aluminum framed stair treads are sprayed with a durable rubber non-skid material that has a professional appearance and offers added safety in all environments, indoor or out.

All stair units can be used with one handrail, two handrails or no handrails and are easily attached or removed. The fixed height and box stair unit handrails are manufactured from steel while the handrails for the adjustable stairs are aluminum.


Fixed Height Stair Units

These stair units are designed to be compact and take less storage space or room on a truck or cart. The stair connects to the stage edge and has two each 2-inch adjustable non-marring screw feet for fine leveling that rest on the floor. A standard 8" rise is on all stair treads but custom heights are available. These stair units are designed for one height only. If stage heights vary from location to location a different style stair unit would be more appropriate.
