2. Increased storage capacity: By reducing aisle width, a narrow aisle racking system can increase the storage capacity of a warehouse by up to 50%.

3. Increased picking efficiency: The use of specialized forklifts and picking equipment designed for narrow aisles allows for faster and more efficient picking.

4. Improved inventory control: Narrow aisle racking systems allow for better inventory control and tracking, as items are stored in a more organized and accessible manner.

5. Enhanced safety features: Narrow aisle racking systems are equipped with various safety features, including anti-collapse mesh and aisle guide rails, to prevent accidents and ensure a safe working environment.
