Back-to-back racking
Short definitionA layout where two rows of racking stand back to back, with an aisle on each side.
A single row goes against the wall and back-to-back double rows go in the middle of the room. Each aisle then serves the racking on both sides and fewer aisles are needed.
A small gap is left between the two rows. It is there for air circulation and to keep the pallets from touching each other.
