What Are RTA Cabinets?
RTA stands for Ready-To-Assemble—also referred to across the cabinetry market as flat-pack, unassembled, or knocked-down cabinets. Over the past decade, RTA cabinets have become the top choice for homeowners, general contractors, real estate investors, and interior designers tackling everything from budget-friendly DIY kitchen remodels to full-scale home renovations.
The core value proposition is simple: at US Kitchen Cabinet, you receive high-end, factory-direct cabinetry equal to or exceeding big-box store quality, but at a fraction of the cost. Because flat-pack shipping reduces bulk and freight fees, we pass those direct savings to you. Best of all, while custom and pre-assembled units often carry long 6-to-8-week lead times, our high-quality RTA cabinets dispatch from our US warehouses in just 2 to 5 business days.

How Our RTA Cabinets Are Built (Materials & Specs)
At US Kitchen Cabinet, we never compromise on structural integrity or material quality. Unlike cheap imported flat-pack units made with particle board or low-density fiberboard, every RTA cabinet line we offer features premium, long-lasting construction:
- Grade-A Solid Plywood Boxes: Constructed with 1/2" to 3/4" real cabinet-grade plywood carcasses and solid face frames—built to resist sagging, moisture, and humidity.
- Dovetail Solid Wood Drawers: 5/8" thick solid hardwood drawer boxes built with interlocking dovetail joints for outstanding weight capacity and durability.
- Soft-Close Hardware Standard: Premium six-way adjustable concealed door hinges and under-mount, full-extension soft-closing drawer glides on every box.
- Durable Baked-On Finishes: Multi-layer polyurethane paint and stain topcoats designed to withstand daily grease, spills, and everyday wear.

Frequently Asked Questions About RTA Cabinets
How difficult is it to assemble RTA cabinets?
Assembly is quick and straightforward. Our cabinet boxes utilize pre-drilled pocket screws, cam-locks, or wooden dowel systems. Most DIYers and contractors assemble a standard cabinet box in 15 to 20 minutes using basic wood glue and a screwdriver.
Are RTA cabinets as strong as pre-assembled cabinets?
Yes. Once fully assembled with wood glue and fasteners, our solid plywood and solid face-frame construction offers identical structural strength, weight capacity, and longevity to factory-assembled units.
What tools do I need to assemble RTA cabinets?
You only need basic hand tools: a Phillips head screwdriver (or cordless drill with torque setting), high-quality wood glue, a tape measure, and a rubber mallet.
