Claim:
A hanger to be mounted to a wall, wherein the said wall can have a non-determined thickness, said hanger comprising: a) a backing plate to be slid through a previously made slot in a wall wherein said backing plate comprises an elongated body comprising a front surface and a back surface, wherein said front surface comprises a substantially flat and hard surface without protrusions, a first front surface distal end and a second front surface distal end, wherein said back surface comprises a substantially flat and hard surface, a first back surface distal end and a second back surface distal end; and a perforation, wherein said perforation is located substantially in the center of said backing plate, wherein said back surface area is bigger than the front surface area, wherein said first front surface distal end is connected to said first back surface distal end by a first tapered portion, wherein said second front surface distal end is connected to said second back surface distal end by a second tapered portion, wherein said first tapered portion and said second tapered portion opposed each other and are located between said back surface distal ends and front surface distal ends, b) a first non-interconnected strip and a second non-interconnected strip, wherein said first non-interconnected strip and said second non-interconnected strip are connected to said front surface, wherein said first non-interconnected strip and said second non-interconnected strip rotates without contacting each other, extends perpendicular to the perforation perimeter and are substantially aligned in a parallel manner so as to define a substantially straight line having said perforation center between said first non-interconnected strip and said second non-interconnected strip, wherein said first non-interconnected strip and said second non-interconnected strip are arranged to be extended perpendicularly to said backing plate and parallel to the outside of the previously made slot opening without contacting the previously made slot inner walls, and c) means for compressing said backing plate to said wall.
