Drive-in and Drive-thru racks have the advantage of being among the most efficient warehouse rack systems in existance. The advantage of using this style of racking is that you can store your pallets extremely close to one another, thus eliminating much of the air space taken up by more traditional storage racks.

Drive-in and Drive-thru Racks are a LIFO or 'Last In First Out' storage system. Pallets are stored and retrieved from the same side in several aisles on several levels. Typically, one of these systems would be employed where shelf life is not a critical factor. Drive in/thru racks also work well in cold storage or freezers. One item to note, however is that where drive through racks can be entered from both sides, drive in racks can only be entered from one side.
