Abstract: A vertically adjustable wall hanger includes a main body that is securable to a vertical surface with mounting screws, nails, or other similar fasteners, and an adjustable bracket. The main body includes a pair of mounting apertures and is generally symmetrical about a plane passing through the axes of the mounting apertures. The main body also includes a vertically-oriented linear ratchet having a plurality of teeth, and a pair of parallel, outwardly-facing, spaced-apart peripheral tracks or grooves. Each of the tracks is open at the top of the main body. The adjustable bracket includes a pair of cylindrical locator pins that enter the tracks at the top of the main body and slide within them. The adjustable bracket also includes a pawl that engages the linear ratchet. The locator pins allow the adjustable bracket to be rotated upwardly, so that the pawl may be disengaged from the linear ratchet, the adjustable bracket moved up or down, and the pawl re-engaged with the ratchet.
