Abstract
Abstract There is provided an improved door structure of the type having a frame supporting a panel of glass or other suitable material and characterized by very narrow stiles. The stiles each have relatively heavy face portions connected by a transverse web and defining confronting shallow and deep glazing pockets. Spaced upper and lower rail assemblies interconnect the stiles, and are each provided with longitudinally extending screw splines. The ends of the upper and lower rail assemblies are coped so that the screw splines fit within the confronting glazing pockets and seat against the respective webs.
