Used pallet rack row spacers provide uniform spacing between rows of pallet rack. When placed back to back, the row spacers are bolted onto to the frame and provide additional support to neighboring rows. It is recommended that you use two row spacers per frame for pallet racks exceeding 6 times the width of your rack. For a used pallet rack measuring 24’ tall, three row spacers per upright is recommended. Used row spacers are easy to install onto pallet rack uprights.
