Abstract: A storage and organization system is provided for customizing existing cabinets, such as kitchen, bathroom, pantry and/or garage cabinets. The system includes differently-sized stationary bases, pullouts, and accessories constructed to fit closely into any of many differently-sized storage spaces for optimal efficiency and maximum capacity, while providing customized functional support. The pullouts slidably extend from track extensions on the stationary bases, and allow side access and top access to selected accessories. The accessories are adjustably mounted on the pullouts for optimal position and function. Components are pre-constructed so that consumers can select and install a system with ease, while still meeting their needs and preferences.
