Abstract: Provided are wall anchors including an external plate and an inside plate partially overlapping the external plate, each of the external plate and an inside plate having a wall-facing side, the plates being rigidly connected to one another adjacent a first end of their respective wall-facing sides by a cylindrical connecting member; at least a portion of the cylindrical connecting member is configured with a round perimeter. Further provided are modifications of such wall anchors.

Abstract: The disclosed subject matter pertains to an artificial panel comprising a spaced apart first wall and second wall. Each of the walls has an inside surface and an outside surface, and at least one fastener location configured at an outside surface of the at least one of the first wall and second wall of the panel. The fastener location is configured for receiving therethrough a fastener and wherein one or more ribs extend between the first wall and the second wall, along at least a portion of the panel, the fastener location being indicative of the location thereof.

Abstract: A plastic panel having channels on both sides, and system and method for producing such panel. For example, a panel is comprised of: first and second walls of plastic interconnected with one another by a set of plastic connecting structures; wherein said walls of plastic are generally parallel to one another and generally perpendicular to said plastic connecting structures; wherein at least one of said walls of plastic comprises an at least one indented channel running generally parallel to at least one of said plastic connecting structures without being in contact with any of said plastic connecting structures.
