Narrow aisle pallet racking is a type of pallet racking system based on the beam-type pallet racking system.
The main distinction of this type of racking is that it has guide rails installed at the bottom to accommodate a "three-way stacker". These rails are typically made of unequal-angle steel, and only specialized "three-way stackers" are able to move along them. Material handling forklifts are not compatible with this type of racking.
