Abstract: A wall anchor socket apparatus for use in securing a wall anchor to a wall having an opening of predetermined diameter formed therein includes a cup-shaped fitting having an open end, a closed end, an intermediate section sized for receipt within the opening, and a circumferential lip adjacent the open end and having a diameter greater than the diameter of the opening. The closed end is adapted to protrude into the opening beyond the wall by a predetermined distance when the fitting is positioned in the opening and the fitting is secured in the opening. A collar is provided having an axially extending sleeve adapted to engage the rear surface of the wall so that the wall is pinched between the lip of the fitting and the sleeve of the collar when the collar is attached to the fitting. A radially extending flange is positioned adjacent the sleeve and is adapted to provide additional holding strength of the apparatus when material is filled around the apparatus against the rear surface of the wall.
