Very Narrow Aisle (VNA) racking is an advanced warehouse storage solution that maximizes pallet storage capacity by significantly reducing forklift aisle width. The system uses adjustable pallet racking combined with floor-mounted guide rails, allowing VNA forklifts or turret trucks to operate safely in aisles as narrow as 1600–2000mm.

This high-density racking system ensures quick pallet picking, individual pallet selectivity, and full use of vertical warehouse space. It is widely used in logistics centers, third-party warehousing, retail distribution hubs, and e-commerce fulfillment centers, especially where warehouse height exceeds 8 meters and pallet turnover is frequent.

Compared to traditional selective pallet racking, VNA systems deliver a storage density increase of over 50%, helping businesses achieve better space efficiency, higher inventory throughput, and lower operating costs.

VNA racking uses special forklifts designed to move through very narrow aisles. These forklifts often have rotating forks for easier handling and are usually guided by floor or rail systems to ensure safe and accurate movement.

The system can also be adapted for order picking, using different handling equipment depending on your workflow.

VNA pallet racking is a popular choice because it’s flexible and helps make the best use of available space. It is especially suitable for warehouses with the following needs:

Quick and easy access to every pallet, while still saving space

Great for different sized items that need to move in and out often

Suitable for many types of products stored on separate pallets

Works well in warehouses with small floor space but high ceilings for tall racks

The main parts of Very Narrow Aisle (VNA) pallet racking are similar to those used in selective pallet racking, as both systems share the same basic structure.

 

A VNA racking setup includes upright frames and horizontal load beams, which together build the main support structure.

 

To meet different storage needs, a range of accessories can be added to VNA racking. Helping to improve safety, efficiency and flexibility, these additional accessories allow the system to be customized to the types of products and materials used in the warehouse.
