Push-back racks, not unlike drive-in racks are designed for a customer who has medium to high pallet volumes of a same SKU. 

All the while providing great density, the added benefit is selectivity as every storage lane can be a different SKU. As Push-back racking is a compacting system, each pallet is loaded onto a wheeled cart guided by rails and pushed back as additional pallets are loaded.  All are custom designed and engineered in a wide variety of heights, widths, depths and weight capacities based on the demands of your specific requirements.
