Fabricated some drawers for it. They can slide right out but are otherwise retained by the runner design.

Different runner heights make it extremely adaptable.

Its best asset is it can live outside. Other benefits; It won’t hold liquids (rain, oils, etc.). I can leave it empty, load it up with tools and work on my vehicles with a place to organise stuff I take off (airfilters, cam covers, trims, fasteners, etc.)
