Very Narrow Aisle (VNA)

Narrow Aisle Pallet Racking

Very Narrow Aisle (VNA) racking is a high-density pallet storage system designed to maximize warehouse capacity by reducing aisle widths and increasing usable storage space.

Require specialized handling equipment in order to load and unload racks. VNA allows more racking rows to fit within the same footprint while maintaining direct access to every pallet.

Instead of expanding your facility, VNA helps you get more out of your existing layout both horizontally and vertically.

Less Wasted Space, More Storage.

Increase 50%
Storage Capacity

VNA racking allows you to significantly increase pallet positions by reducing aisle width and optimizing layout efficiency. In a traditional setup, wide aisles are necessary for standard forklifts to operate. With VNA, those aisles are minimized, allowing more racking rows to be installed within the same floor area.

This results in a substantial increase in storage density, often adding 30 to 50% more capacity without changing your building footprint. For many operations, this means delaying or avoiding the need for costly expansion or relocation.

Maintain Full Pallet Access
with a Structured Layout

VNA maintains direct access to every pallet location. This makes it well-suited for operations with a high number of SKUs or inventory that needs to remain organized and easy to retrieve.

The narrower aisles also create a more structured and consistent layout, helping improve inventory control and overall organization. Each aisle is clearly defined, supporting a more controlled and efficient flow of movement within the warehouse.

Designed for Predictable,
Efficient Operation

VNA systems are built to work with specialized narrow-aisle equipment, allowing operators to move efficiently within tighter spaces without the need for wide turning clearance. Movement is more controlled and aligned with the aisle layout, supporting safe and consistent operation.

Combined with the ability to utilize vertical space more effectively, VNA creates a storage system that balances high density with reliable performance.

FAQ

Very Narrow Aisle (VNA) racking is a high-density storage system designed to reduce aisle widths and increase pallet storage capacity within an existing warehouse footprint. It allows more racking rows to be installed while still maintaining access to every pallet.

VNA reduces the amount of space needed for forklift aisles, allowing that reclaimed space to be used for additional racking. This can significantly increase pallet positions compared to traditional wide-aisle layouts.

Standard forklift aisles typically require much wider clearance, while VNA aisles are significantly narrower and are designed specifically for specialized narrow-aisle equipment to operate safely and efficiently.

VNA systems are typically operated using specialized narrow-aisle forklift designed to work within tight aisle spaces, allowing precise pallet placement and retrieval.

 

No. VNA is best suited for operations that need higher storage density and have stable, structured workflows. It may not be ideal for facilities that require constant, high-speed access across multiple aisles at the same time.

The main difference is aisle width and storage density. VNA reduces aisle space to maximize storage, while standard pallet racking uses wider aisles for conventional forklift access and flexibility.

In many cases, yes. VNA is often implemented in existing facilities as a way to increase storage capacity without requiring relocation or building expansion.
