Very Narrow Aisle Racking by NAS consists of the same basic components as Selective Racking, but the access aisles are greatly reduced resulting in increased use of existing cubic space.

In this case loading and picking is mostly done by rail or wire guided Swing Reach and Picker Trucks.  All picking locations can be accessed throughout the full height and length of the system. 

Pallets can be stored to greater height for more effect use of storage space, but very tall installations may require a ‘super flat'  floor to allow safe equipment access.
