ABSTRACT:
The guardrail assembly includes at least two tubular metal stanchion posts having a base, at least one aperture through one side of each stanchion post and at least one horizontal rail having a fastener at each end for extending into the respective stanchion post apertures. The horizontal rail has an inner metal pipe, an outer plastic pipe, and an end plate for supporting the fastener. Following insertion of the fastener of the horizontal rail into the stanchion post aperture, a threaded nut positioned in each stanchion post engages the threaded fastener at each end of the horizontal tubular rail to retain the fastener within the stanchion posts. In one embodiment, a tubular plastic sheath having at least one aperture is slipped onto the tubular metal stanchion post having at least one aperture and the apertures are aligned to form a stanchion having an aperture prior to insertion of the fasteners into the stanchion apertures. In an alternative embodiment, the stanchion has a plurality of apertures for receiving the fasteners of a plurality of horizontal rails. In a preferred embodiment, the stanchion has an upper set of horizontally aligned apertures and a lower set of horizontally aligned apertures where, most preferably, the upper apertures are also aligned vertically with the lower apertures.
