Abstract: The present invention serves to anchor appurtenances to wallboards without requiring a hollow void or cavity behind the wallboard and providing a secure stable attachment. In preferred embodiments, the wallboard anchor of the present invention has an arcuate shank or prong, having a distal point, that is inserted into the wallboard on an upward curved path, a wall engaging portion proximate the arcuate prong contacts and engages the outer surface of the wall. Preferably, the wall-engaging portion presents a vertical flat surface and the arcuate prong extends directly from the flat surface of the wall-engaging portion, initially perpendicularly from the, and then sweeps upwardly with a radius of curvature. The radius of curvature is preferably about equal to or less than the thickness of the wallboard to which the appurtenance is attached.
