Not a small spiral stair, the 78″ circular staircase has a larger diamerer center pole and can be combined with a round metal inner handrail (at 8″+ radius). This spiral stair and its larger counterparts can all have outer guard rails handrail and sub-line handrails in concert with the inner handrail without severely impacting traffic. When outfitted with the outer handrail alone, this stair provides the full 36″ clear that one might find on a traditional staircase. This is the smallest spiral stair that uses a 4.5″ O.D. tread sleeve & 4″ center column pole as a standard.

We have an 84″ diameter space enclosed space reserved for a spiral stair. The floor to floor height is 108″. How much would your staircase cost?
