RTA Kitchen cabinets often use ready-to-assemble (RTAS) hardware, rather than costly and labor-intensive cabinet hardware. Because RTA cabinets require standard drawer slides, drawer fronts, and door hardware, the cost of the raw materials is significantly reduced. RTA kitchen cabinet sets also offer significant cost savings over wood cabinets. Most wood cabinets are assembled in a warehouse and stored for much of the year. This means they are never exposed to the elements or temperature fluctuations, such as those found in a kitchen.
