Can I stack multiple boxes on top of each other?

The modular design supports stacking for warehouse or shop organization. Just make sure the load on lower boxes doesn't exceed safe weight limits — start light and add gradually to test stability.

Will this crack or fade in hot sun?

Plastic does weaken over time in intense UV exposure. Keep it in a shaded bay or covered area for longest life. The red finish may fade slightly after years of direct sunlight, but the box will remain functional.

What size items can this hold?

Interior dimensions aren't specified, so test-fit your most common tools before committing to this as your primary storage. Most techs use these for fasteners, wrenches, and smaller hand tools rather than large power equipment.
