Abstract: An apparatus for height adjustably supporting an object on a wall surface includes a horizontal wall mount spacer section adapted to be mounted adjacent a wall surface. An object support rail is adapted to be mounted adjacent the wall mount spacer section opposite the wall surface, the wall mount spacer section and object support rail mounted in substantially parallel alignment. The support rail has a saddle-receiving upper surface spaced from the wall mount spacer section. At least one object-supporting saddle bracket is provided, the bracket adapted to fit over and be supported by the upper surface of the support rail, each bracket further including engagement hooks for engaging and supporting an object adjacent the outer side of the support rail. Mounted on the object to be supported is a receiving element such as a double slotted standard which will receive and retain the engagement hooks thus allowing an object to be supported by the wall mount apparatus.
