• and
• at least two hooks movably coupled to said plate positioned adjacent to second and third corners, respectively, of said plate, wherein each hook is passed through a hook opening that is of a smaller size than the opening of the securement structure, wherein a base end of each hook is spaced apart by a natural number multiple of a hook spacing distance, wherein the hook spacing distance is between about 1¾ inches and about 2¼ inches, or is between about 2¾ inches and about 3¼ inches, wherein each hook is generally “S”-shaped, wherein each hook opening non-removably directly receives the base end of an associated hook therethrough, wherein said plate is generally shaped as non-equilateral isosceles triangle in front view, wherein said securement structure is positioned adjacent to a vertex of said triangle defined by said first corner, and wherein each hook is positioned adjacent to a base edge of said triangle, wherein the system further comprises a supplemental hook movably coupled to said plate, and wherein a base end of said supplemental hook is spaced apart from at least one of said two hooks by said hook spacing distance, and wherein said base end of said supplemental hook and said base ends of said two hooks are all positioned adjacent to a same edge of said plate, and wherein said plate is made of metal and has a thickness of less than about ¼ inch.
