Ready-to-Assemble (RTA) Cabinet Boxes

Our Ready-to-Assemble (RTA) Cabinet Boxes are pre-engineered, pre-sized cabinets built for speed, consistency, and professional results.

These are not custom box builds — each cabinet is manufactured to standard configurations, CNC-cut for accuracy, and shipped flat-packed to reduce shipping costs and handling damage. Assembly is straightforward, fast, and designed for real jobsite or shop conditions.

Looking for custom cabinet boxes?

Custom sizes and configurations are available but must be ordered through our Custom Quote Request page.

Whether you’re outfitting a full kitchen or filling in a single cabinet, these boxes give you a solid, square foundation that pairs perfectly with CabFit custom doors and drawer fronts.
