double-deep rack

Double Deep Racking stores two pallets deep, or four pallets deep in a double entry rack. Double entry racks reduce the aisle to rack ratio but also reduces pallet selectivity, increasing storage density.

*0% immediate pallet access provides reasonable stock rotation on a FILO (First In Last Out) basis and makes good use of all available locations. This system is best used when each SKU has several pallets.

The system requires the use of a special reach truck with either dual pantograph or slide fork attachments. Truck lift heights are limited by load to about 9 meters.
Upper levels can be fitted with guide rails to assist forklift drivers in locating pallets; They also help reduce fork truck operator error and accidental impact damage.
