Stairs Highlights
Quality. Safety. Value. With Century's Windsor Wood Series, you get ultra-dependable folding stairways that are big on features, at an affordable cost. Constructed of kiln-dried southern yellow pine for superior strength and rigidity, this stairway has a 250-lb. load rating. It also touts Century's user-adjustable red nut J-bolt technology allowing you to safely adjust your door panel while the stairway is pulled down. With all other products on the market, you must be in your attic, close the stairway door, then dangerously pull out the spring to make the adjustment. The molded handrail and eased-edge stiles enhance the appearance and add the finishing touches to this superior pull-down stair product.
