VNA
RACKING
Very Narrow Aisle systems maximize vertical storage capacity while minimizing aisle width. Purpose-built for high-density, high-throughput warehouses where floor space is at a premium.
Why VNA RACKING?
The Problem
You’ve maxed out your selective racking layout but still need more storage. The building is full, the lease is locked, and adding a second shift won’t create more pallet positions. Your per-position cost is climbing as inventory grows.
Why It Gets Worse
Conventional racking requires 10-12 foot aisles for standard forklifts. That means 50% or more of your floor space is empty air. In a 50,000 sq ft building, that’s 25,000 sq ft of paid-for space storing nothing. At $10/sq ft, you’re spending $250,000 a year on aisles.
The Solution
VNA racking cuts aisle width to 5-6 feet using specialized turret trucks or swing-reach forklifts. The result: 40-50% more pallet positions in the same building. Wire guidance or rail guidance keeps equipment running safely in narrow lanes. Taller configurations (up to 45’) stack vertically where conventional racks can’t reach.

Why Choose 416 Industrial
40-50% More Pallet Positions
Cut aisle width from 12 feet to 6 feet. That recovered space becomes productive storage, not empty air.
Full Selectivity Maintained
Unlike drive-in or push-back, VNA gives you instant access to every single pallet position. No LIFO compromises.
Avoid Facility Expansion
Add thousands of pallet positions to your existing building. Defer or eliminate the cost of a second warehouse.
Automation-Ready
Wire-guided VNA systems integrate with automated guided vehicles (AGVs) and warehouse management systems (WMS) for lights-out operation.
Frequently Asked Questions
VNA systems require specialized turret trucks or swing-reach forklifts designed for narrow aisle operation. These trucks feature rotating masts that place and retrieve pallets without turning in the aisle. Equipment costs $80,000–$200,000 per truck depending on capacity and automation level.
Most VNA systems operate in 5–6 foot aisles, compared to 10–12 feet for conventional forklifts. The exact minimum depends on pallet size, truck model, and rack depth. We specify aisle width as part of the system design.
VNA systems cost 20–40% more than equivalent selective racking due to tighter tolerances, guidance systems, and specialized equipment. However, the 40–50% increase in pallet positions typically delivers a lower cost per position and rapid ROI through avoided facility costs.
Wire-guided offers higher precision, smoother operation, and no floor obstacles, making it ideal for new construction. Rail-guided is less expensive, works on uneven floors, and is easier to install in existing buildings. We recommend wire for new facilities and rail for retrofits.
VNA systems typically need 25–50 foot clear ceiling height to maximize the vertical storage advantage. The exact requirement depends on your pallet height, beam spacing, and top-of-steel clearance requirements. We perform a complete building assessment during design.
