Drive-in, Drive-Through racking consists of a continuous block of racking up to 10 metres high, undivided by aisles. Trucks can drive right into the centre of the block between any uprights on the front face to pick up pallets. This is possible as the design does not require cross beams which would block entry. Instead, the pallets are supported on the left and right sides by continuous rails cantilevered from the uprights at each pallet level.
