Ive only been in the one big ass distribution center, so it's cool to see the same system is fairly standardized. Looking at it, this is MUCH smaller. The mezz I've worked with is 4 pallets deep on either side. They are on slightly angled rollers, so they "replenish" when an empty pallet is removed.

Most of our product is larger parts, so we probably don’t have as much need for the smaller pick modules. We have many larger aisles of palettes going 40’ up.
