Adjustable shelving

Adjustable shelving allows more flexible use of shelves to hold items of value for storage, display or sale. Like fixed shelves, the horizontal planes are normally made of strong materials such as wood or steel (occasionally glass or other materials), but their exact vertical positioning can be varied - usually through the use of uprights into which supporting brackets or the shelves themselves can be fixed at different heights.

For example, in furniture such as a cabinet or bookcase, the vertical elements may be drilled to allow metal or plastic supports to be inserted, and the shelf then rests on the supports. Alternative approaches include the use of grooves on the uprights at either end of the shelf into which the shelf can be inserted.
