Compact Double Vertical Lift Module
Maximum SKU density in the smallest footprint
The Compact Double is built for facilities that need to consolidate large inventories into less floor space. Its dual-tray elevator and four-tray-per-level layout help maximize storage density while keeping items organized and accessible.
- Store more SKUs in one vertical module
- Reclaim up to 85% of floor space
- Bring items to the operator at an ergonomic height

The Compact Double is designed for facilities that need high-density vertical storage without spreading inventory across rows of shelving. The video shows how the dual-tray elevator and four-tray storage layout work inside the module.
Is the Compact Double the right VLM for your facility?
Best fit when you need:
- Maximum storage density in a limited footprint
- High SKU consolidation in one vertical module
- Organized tray storage for parts, tools, components, or inventory
- Goods-to-person access at an ergonomic height
- A VLM option for facilities where floor space is the main constraint
A different VLM may be better if:
- Your priority is the fastest tray delivery
- You need very large or heavy trays
- You are comparing lower-cost entry points into automated storage
- You need help choosing between density, speed, tray size, and budget

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.
