Carton Flow Rack Suppliers — 24 US Companies
Carton flow is pallet flow's smaller sibling — gravity-fed roller or wheel tracks built into rack shelves so cases and cartons roll forward as you pick from the front. It turns a static pick face into a self-replenishing one, cutting walk time and keeping the most-picked items within arm's reach.

When to Choose Carton Flow Rack
- ✓Each-pick or case-pick operations with high SKU counts
- ✓Order pickers spend too much time walking between picks
- ✓You need a self-replenishing pick face that stays organized
- ✓FIFO rotation at the carton level is required
- ✓You're designing a pick module or mezzanine pick area
Key Specs to Ask About
- •Track type (wheel rails, full-width rollers, or tilted shelf inserts)
- •Lane width (sized to your carton/case dimensions)
- •Number of lanes per shelf level
- •Shelf depth (typically 3-6 cartons deep per lane)
- •Knuckled tracks or flat — knuckled helps with heavier cartons
- •Integration with pick-to-light or voice-pick systems
Common Applications
- •E-commerce piece-pick and pack stations
- •Grocery and convenience store distribution
- •Auto parts picking operations
- •Pharmaceutical unit-of-use dispensing
- •Any pick module with high picks-per-hour targets
How It Compares
| Factor | Carton Flow | Static Shelving |
|---|---|---|
| Replenishment | Self-replenishing — gravity feeds product forward | Manual — must restock shelf positions |
| Pick speed | 250-400+ picks/hour achievable | 80-120 picks/hour typical |
| Best for | High-volume each-pick and case-pick | Low-velocity items, parts rooms |
| Cost | $$$ (flow tracks add to rack cost) | $ (basic steel shelving) |
| Space efficiency | Moderate — lanes are sized to carton dimensions | High flexibility — any item on any shelf |
Carton flow makes sense when pick speed is the priority — the gravity-fed lanes keep product at the pick face without manual restocking. Static shelving works for lower-velocity items where the simpler system is adequate. Most pick operations use both — carton flow for fast movers, shelving for slow movers.
Buyer Tips
Map your carton dimensions before spec'ing lane widths. Mixing wildly different carton sizes in a carton flow system leads to jams and wasted space.
Tilted shelf inserts (drop-in flow tracks) are a cheap way to add carton flow to existing selective rack without replacing the entire shelf level.
Front stops matter. Without them, cartons roll off the pick face onto the floor. Seems obvious, but it's a common oversight in initial designs.
Consider ergonomics. The best carton flow designs put the highest-velocity SKUs between waist and shoulder height. Knees and overhead are for slow movers.
The best carton flow operations achieve 250-400+ picks per person per hour. A static shelving setup doing the same SKU count is lucky to hit 100.
Frequently Asked Questions
What's the difference between carton flow and pallet flow?
How much does carton flow rack cost?
Can I retrofit carton flow into my existing rack?
How deep should my carton flow lanes be?
Before carton flow existed, order pickers in the 1960s walked an average of 12 miles per shift. That's nearly a half marathon, five days a week, in steel-toed boots.
