Abstract: Apparatus for facilitating the installation of a modular cabinet assembly on a wall includes two adjustable height lifting and leveling assemblies each having a base portion positionable on the floor. An upper portion of each assembly has spaced structures useable for receiving sections of two elongated, horizontally spaced apart support members which extend parallel to one another and to the wall. With the assemblies in a horizontally spaced relationship with one another and secured to the wall, and a plurality of cabinet modules resting on top side portions of the support members, the modules are secured to one another, and the resulting assembly is leveled about axes perpendicular and parallel to the wall by using leveling portions of the assemblies to vary the heights of the support member sections disposed in the receiving sections. The leveled cabinet assembly is then anchored to the wall.
