This IP relates to an innovative wall system for pre-finished panel installation which includes a stud and floor/ceiling track which index each other for precise stud location. A tab and slot design between the track and stud assures exact alignment. A horizontal cleat which receives an indexed slot in the back of the prefinished panels is inserted into pre indexed slots in the vertical stud. This system allows panels and modular systems such as bookcases and cabinets to be installed on the face of the wall or into the depth between two studs as well. This is a versatile system which guarantees panel alignment, and it is proposed to eliminate drywall from the manufactured architecture industry.
