When trying to maximize the usability of a corner space in an L-shaped or G-shaped cabinetry floor plan, designers will often call for pie cut shelves to be installed. The dimensions available are suited to full sized base cabinetry space. To operate a pie cut shelf, the cabinet doors are opened and the individual shelves are rotated to access whatever one is in search of, but the shelf must be rotated back to its original alignment before the cabinetry door can be closed. This is the source of the most common complaint by those that choose to have this style of shelving installed. Aligning the shelves can be frustrating if the bearings rotate too effortlessly, but if the bearings are too rigid then convenience is inhibited.
