Harbor Freight Modular Toolbox Trays

**Tray System for Harbor Freight Modular Rolling Toolbox**

This set of trays is designed specifically for the [Harbor Freight Modular Rolling Toolbox](https://www.harborfreight.com/modular-rolling-toolbox-58512.html). They are practical for various uses, from organizing tools to holding and transporting games like Heroscape.

### Key Features
- **Custom Fit:** Each tray has notches that align with the toolbox's channels, preventing movement during transport.
- **Durable Construction:** These trays are thick and rugged, suitable for tools or gaming components.
- **Tapered Toolbox Design:** The toolbox is slightly wider at the top than at the bottom. This tapering means most trays fit only in specific vertical positions, which are marked with numbers for proper stacking.
- **Smooth Operation:** The trays slide in and out with some tolerance but may feel tight if the toolbox isn’t on a level surface. However, they are never too tight to remove.
