Abstract: A support for a hollow post of the type used to support horizontal rails for railing or fencing systems, and having a hollow, constant cross-section, the support comprising a rigid support member, such as a steel pipe, having upper and lower end portions, the lower end portion adapted to be fixed in vertical position while the upper end portion extends within the hollow post. At least one spacer, preferably extruded from plastic material or aluminum, has a tubular portion with an inner bore sized to snugly receive the rigid support member, and has longitudinal protrusions, for example ribs, ribs projecting outwardly from the tubular portion and suitable for firm engagement within internal cavity of the post. The ribs provide clear spaces between the post wall and the tubular portion which are suitable for receiving end portions of the rails when inserted into apertures formed in side walls of the post.
Abstract: An elongated member suitable for flooring, decking, or seating, having a top plate formed as an extrusion of plastic material, wherein the top plate includes ribs constituted by protruding parts of parallel, spaced, elongated friction elements co-extruded therewith, the friction elements being formed of plastic having distinctly greater softness or flexibility than the main parts of the top plate and suitable for providing a non-slip surface. The member may include an elongated support formed as a relatively rigid extrusion of plastic material having a base plate with upstanding side walls and a central support portion, the top plate overlying the support and having edge formations engaging the side walls. Alternatively, the top plate and support may be formed integrally by extrusion, or the top plate may be part of a plank cover having integrally formed ribs for spacing the top plate above a plank.

The member may include an elongated support formed as a relatively rigid extrusion of plastic material having a base plate with upstanding side walls and a longitudinally extending upstanding support portion positioned between the walls, the top plate overlying the support and having edge formations engaging the side walls. The top plate and support may be formed integrally by extrusion.

Abstract: A window frame member formed as a hollow extrusion of rigid plastics material has a hollow space partly defined by a wall portion including two opposed, undercut lips and a web interconnecting the lips. Internal grooves are provided along the junctions of the web with the lips to provide lines of severance allowing the web to be readily removed so as to provide a slot between the edges of the lips. Preferably, the web and adjoining parts of the lips have a smooth, uninterrupted exterior surface. This invention allows the frame member to be used either with the web in place, in which case there is no slot or observable discontinuity in the exterior wall, or with the web removed where it is desired to provide a slot for weather stripping or attachment of adjacent pieces. The web may be readily removed with simple tools.
