This layout also saves space as fewer aisles are required. Selectivity is typically around 50% and assumes all goods are uniform and on standard pallets. Double deep installations are quickly and safely assembled even at great heights.

Conventional trucks can be used in conjunction with a pantograph attachment allowing the forks to place the pallet in the rear rack location. Telescopic forks can also be specified but require extra space under the pallet. This is achieved by supporting the pallets on front to back supports mounted on the beams.
