Fixed shelves are non-adjustable shelves that are permanently attached to the frame in a manner that cannot be changed. These shelves are suitable for storing items that have a standard height, such as notebooks and CD cases. The height of fixed shelves cannot be modified to accommodate larger or smaller items. Fixed shelves are commonly used in areas where the storage items have a relatively uniform height, such as stacked plates or in closets and open spaces. In cabinets, the use of fixed shelves can limit access to the back of the shelf, leading to frustration. However, in closets, homeowners have more freedom of movement to access the entire area of the shelf. Fixed shelves are attached to the surface using metal brackets, which provide support for the shelves.
