  • Patent number: 5112022
    Abstract: A frame hanger (1) is provided which includes a plastic element in the form of a hook which includes a base portion (13) in the region where it attaches to a wall. The frame hanger also includes a nail (2) which is frictionally engaged by a passage formed longitudinally through the frame hanger for attachment to the wall. The nail initially protrudes only from the front of the frame hanger in order that the base portion may initially be placed firmly in contact with the wall. The frame hanger is attached to the wall by driving the nail (2) through the frame hanger and into the wall until the nail does not protrude from the front of the frame hanger. An auxiliary plate (3) is provided to assist in holding the frame hanger in position against the wall during driving of the nail. The body of the frame hanger includes a cylindrical portion (11), a widened portion (13) at the base and a salient portion (12) at the opposing end of the cylindrical body.
