Pick Module
What is a Pick Module?
A pick module is a single or multi-level engineered system designed to streamline order fulfillment by strategically storing SKUs within a warehouse. These systems use a combination of dynamic and static storage solutions — such as carton flow, pallet flow, shelving, and conveyors — to move products efficiently through the picking process.
By organizing SKUs based on throughput (slow, medium, and fast movers), pick modules maximize space utilization, reduce picker travel time, and increase both speed and accuracy across operations. An optimized pick module integrates the right mix of storage mediums, configured to reduce wasted motion and streamline workflows.
Where are Pick Modules Used?
Warehouse pick modules are used in high-volume order fulfillment environments where speed, accuracy, and space optimization are critical. They are widely adopted across industries including:
No matter the industry, a well-designed pick module helps organizations improve throughput, reduce costs, and better utilize warehouse space.

Benefits of a Pick Module
The ultimate goal of any fulfillment operation is to increase speed while driving down costs. A strategically designed warehouse pick module supports lean, efficient operations by:
- Reducing labor costs through shorter travel distances and optimized pick paths
- Improving order accuracy with clearly organized and easily accessible SKU storage
- Maximizing space utilization by leveraging vertical storage and dynamic systems
- Enhancing safety and ergonomics by minimizing reaching, lifting, and congestion

Best Practices for Optimizing Warehouse Pick Modules
To get the most out of your pick module, it’s not just about installing storage — it’s about designing a system that aligns with SKU movement, enhances picker performance, and maximizes space. These best practices can help you create a faster, more efficient order fulfillment process:
1. Slot SKUs by Throughput: Classify SKUs as slow, medium, or fast movers. This ensures the right products are placed in the right zones — cutting search time, reducing congestion, and boosting pick speed.
2. Match Storage to SKU Type: Once SKUs are categorized, choose storage solutions that match their movement. Slow movers benefit from compact, shelving; medium movers are best suited to organized carton flow systems; and fast movers belong in pallet flow lanes for quick access and replenishment.
3. Use Conveyors for Flow: Incorporate gravity conveyors to move picked items between zones or to packing. This reduces walking, speeds up order flow, and keeps pickers focused on picking.
4. Design for Ergonomics: Ensure SKUs are easy to reach and picks don’t require bending or stretching. Use angled shelves and mobile carts like SpeedCartt to improve comfort and reduce fatigue.
Increase SKU Density with UNEX Pick Module Solutions
To get the most value from your pick module, it's essential to optimize storage based on SKU velocity. UNEX offers dynamic, high-density storage solutions that help you fully utilize every inch of your warehouse space without overhauling your existing infrastructure.
For slow-moving SKUs, the SpeedCell high-density storage system is a game-changer. This high-density solution fits neatly into standard pallet racks, compressing storage space by up to 60% and reducing labor costs by as much as 40%. SpeedCell transforms unused vertical space in your pick module into an efficient, organized zone for infrequently picked items.
For medium movers, SpanTrack carton flow rack systems provide a flexible and powerful way to improve picking performance. These drop-in tracks fit into existing pallet rack structures and create a smooth-flowing pick module that increases throughput by up to 150%. Choose from dedicated roller lanes, universal wheel beds, or a combination of both to create the ideal configuration for your operation.
