SpanTrack is a gravity-fed carton-flow track from UNEX that drops into existing pallet racks. It creates high-density picking lanes where boxes and cases glide to the front for fast, orderly retrieval.

What's the difference between SpanTrack and carton or case flow?

Carton or case flow is the general category of gravity systems that feed products forward for picking, while SpanTrack is UNEX’s specific version that installs directly in pallet racks and uses full-width steel rollers for smoother, more durable flow than traditional wheel rails.

What is SpanTrack used for?

SpanTrack builds gravity-fed picking lanes inside pallet racks to keep products automatically flowing to the pick face. It’s used for FIFO inventory rotation, quicker order picking, and reduced travel time in warehouses, fulfillment centers, and manufacturing areas.

Frequently Asked Questions

SpanTrack is a gravity-fed carton flow system made by UNEX that drops into existing pallet racks to create efficient, high-density storage and picking lanes. It’s commonly used in warehouses and fulfillment centers to speed up order picking, reduce travel time, and improve inventory visibility.

The main difference is that SpanTrack is a specific type of carton or case flow system, designed by UNEX to retrofit directly into existing pallet racks without the need for shelves or additional supports. While carton or case flow refers broadly to any system that uses gravity to move products forward for picking (typically using wheel rails or rollers), SpanTrack uses full-width steel rollers that provide better product contact, smoother flow, and more durability than traditional plastic wheel rails.

SpanTrack is used to create gravity-fed picking lanes within pallet racks, allowing cartons, cases, or other inventory to automatically flow to the front for easy access. It's ideal for order picking, inventory rotation (FIFO), and improving efficiency in warehouses, fulfillment centers, and manufacturing environments where fast, organized access to products is needed.
