Abstract
Abstract A metallic railing assembly, comprised of vertical posts, horizontal rails and pickets of extruded aluminum or alloys thereof, which are interconnected by means of bolts and screw fasteners without welding procedures. Splines of special and simple construction, which are severed from a length of extruded alloy, are affixed to the posts to provide a secure support for the ends of the rails to transmit the horizontal loadings to the anchored vertical posts, without loosening any of the component parts.
