Abstract: A wall anchor assembly and method of installing such to a wall assembly, ceiling assembly, door, or other surface. The wall anchor assembly generally includes a thin line anchor which includes a drill guide, a threaded receiver, and a pair of cord holes. A flexible cord is threaded through the cord holes and can be used to position the anchor on the interior face of a wall assembly once a hole is drilled using the drill guide located on the anchor and the anchor has been inserted through the drilled hole. The anchor may be made from cutting a flat bar or stamping, milling, extruding, or molding the anchor from steel, aluminum, or plastic.
