A wide range of accessories such as shelf dividers, stackable ledges, drawers and slides, rods and tabs, bin markers, and more, let you customize MetroMax to your exact needs. Shelves are adjustable at 1/2" (13mm) increments along the height of the numbered posts. Solid and open-grid shelf mats lift off the shelf frame for cleaning away from the site.
