Pick Module

What is a Pick Module?

Pick modules are multi-level, engineered systems comprising various storage mediums designed to move SKUs throughout a fulfillment operation. These systems utilize several space-saving solutions to store SKUs according to throughput.

By examining the total SKUs within your warehouse and analyzing slow-movers, medium-movers, and fast-movers, you can determine the perfect combination of storage mediums to assign each SKU to its optimal position (or slot). In a high-performing order picking operation, pick module systems use various static shelving, tilted pick shelving, high-density storage, carton flow, pallet flow, and conveyors. Implementing these solutions creates maximum order picking efficiency and increases SKU density.

Where are Pick Modules Used?

Pick modules are strategically designed to improve overall performance within order fulfillment operations. A highly effective pick module aims to optimize the cubic space within a warehouse to minimize the amount of time order pickers spend searching for and picking SKUs to fulfill orders.

The use of a warehouse pick module is beneficial to operations across industries including:

Pick Module Benefits

The ultimate goal of any fulfillment operation is to increase speed while driving down costs, and a thoughtfully designed warehouse pick module is a significant part of achieving that goal.

  • Reduce labor costs by minimizing travel distance and time between picks
  • Increase order picking accuracy by consolidating and organizing SKUs
  • Maximize space utilization by consolidating SKUs and using vertical space
  • Improve safety and ergonomics by separating forklift areas from picking aisles

Best Practices to Improve Pick Modules

With the right combination of storage solutions, you can create a multi-level pick module that condenses and organizes SKUs to enhance overall productivity within your operation. When designed correctly, pick modules will maximize space within your facility and reduce search and travel time.

Increase SKU Density with Pick Module Solutions


Implementing a SpeedCell dynamic industrial shelving system is ideal for the slow-moving SKUs within your operation. A necessary part of any order picking operation, high-density storage solutions like SpeedCell can increase storage density up to 60% and reduce labor costs up to 40%. SpeedCell can be installed into an existing pallet rack to transform unused space in your facility into highly efficient storage.

UNEX’s SpanTrack carton flow systems are ideal for medium-moving SKUs. This innovative carton flow solution drops into existing pallet racks to create a robust flow system for any operation. Whether you’re looking for dedicated roller lanes, universal wheel beds, or a combination of both, SpanTrack can maximize space within your facility and increase throughput up to 150% compared to picking from a pallet.
