Each Gemtrac unit comes with a left and right bank of drawers, these get divided into two groups of Zones. In this example we will use Red and Green colors to identify the Zones correctly.

Focusing on the Red bank, each drawer is identified as a Zone. First drawer would be Red-1, second drawer Red-2 etc. Start at the end opposing to where you will put any expansion Gemtracs to ensure the new additions are in successive numerical order.

Labels for the Gemtrac drawers are printed onto card stock and placed in the card holders, ensuring the barcode is fully visible and not obstructed by the holder frame.

Shelf number labels for each shelf are applied to a conspicuous location along with Slot numbers. The image shows Slots numbered in ranges, but how you label the Slots depends on personal preference. Every Slot can be numbered individually, in ranges, every second shelf etc.
