Adjustable shelving

An adjustable shelf is a shelf that can be adjusted according to needs. The most common variant is that the height intervals can be adjusted to accommodate various items. This allows more flexible use 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 (and occasionally glass or other materials), but their vertical positioning can be varied – usually through small, exact holes into which the supporting brackets have been inserted, or in an older method, slots which are an integral part of the cabinet itself into which the shelves are inserted.^{[1] [2]}

Adjustable shelves are available in many variants. Pallet racks as found in modern warehouses are some of the toughest and most durable adjustable shelves, being designed to bear extremely heavy industrial loads on pallets.
