Single deep pallet rack, also known as selective rack, is by far the most common type of rack used in warehouses today. Because pallet loads are stored only one pallet deep, single-deep rack provides the lowest density storage of any pallet racking system.
Single deep selective racking remains popular, however, because it permits unimpeded access to every pallet it stores. Additionally, single-deep rack can be used in a variety of aisle configurations and can be paired with any type of lift truck and is the least expensive style of rack.
