Our steel stair tower landing platforms are manufactured for single or multiple height access. Stairways can enter or exit the landing from any side. Landings are provided with easy to install 3-rail guard rails and kick plates for any two sides as required. Guard rail will not allow a 12 inch sphere to pass through. Check your local codes - a 4, 5, or 6 rail system may be required. Units are shipped knocked down for freight savings. Note: Landing platform width dimension must be at least 12” wider than the stair tread width to allow for ample hand clearance.
