VNA Wire Guidance

A very narrow aisle, otherwise known as VNA, is the use of selective pallet racking in a tighter configuration to provide maximum space utilization within a storage facility. These systems typically operate in conjunction with wire-guided or rail-guided reach-truck systems.

A wire-guided system consists of a wire embedded in the concrete floor that provides tracking for the reach-truck. A rail-guided system consists of angle iron bolted to the floor down the length of each row. Typically, the angle iron is 4” by 3” and ¼” – ⅜” inches thick. A distinct advantage of a narrow aisle pallet racking is fast picking without large aisles which results in improved use of space.

When there is limited space, a compact storage method is ideal. Fully adjustable system flexibility and space saving aisles can be manipulated as one to give the greatest amount of pallet storage locations.
