Built for Maximum Inventory Consolidation
The Compact Double is the ideal solution for facilities managing massive SKU counts that require total organization in a restricted footprint. By utilizing a 4-tray horizontal configuration and an intelligent dual-tray elevator, it allows for the highest possible storage volume per square foot. It is the ‘Master’ unit for high-density storage, designed for operations where floor space is the most critical constraint.
