The Blum METABOX 320M is a steel drawer side and slide kit in White finish, pairing a 16 inch (400mm) runner with a 3-3/8 inch tall drawer side in one matched set. It is built for cabinet shops and installers fitting painted or white-laminate interiors where the drawer hardware needs to disappear into the cabinet box.
A white interior finish matters most in painted-shaker and slab-door kitchens where every visible surface inside the cabinet is white or off-white. The METABOX 320M's White profile sits flush against a white-painted box and lets the drawer front carry all the visual work. It is equally at home in laundry rooms, bathroom vanities, and utility cabinetry where a crisp, clean interior is part of the design intent. Shops running white-finish kitchen lines in volume find the matched set format reduces sorting at assembly — the runner and side come together and go into the drawer as a unit.
The METABOX 320M side profile is formed steel finished in White. The system is a single-wall design — lighter and more economical than double-walled platforms — suited to standard residential and light commercial drawer loads. At 100 lb rated capacity, it handles the full range of kitchen drawer contents comfortably. The motion technology on this kit is standard, meaning the closing action is mechanical and self-closing rather than damped. The drawer closes on a ramp or detent, not a soft-close damper — a positive close, not a slow-motion one. Shops specifying soft-close damping should confirm their SKU selection against the METABOX line's soft-close variants before ordering.
Cabinet shops building painted kitchen lines in white or off-white are the primary buyer: the finish match removes any risk of a steel-gray side showing at the drawer opening. Remodeling contractors sourcing drawers for a white painted vanity or utility room find the 16 inch length covers the most common shallow-depth cabinet without cutting down a longer slide. Custom woodworkers who prefer a metal side system over a built-wood drawer box use the METABOX 320M where the budget calls for a reliable single-wall system rather than a premium double-walled platform. The 3/4 extension suits storage drawers — spice drawers, linen drawers, shop supply drawers — where full rear access is less important than a clean look and solid capacity.
This is a Drawer Side and Slide Kit — the steel side profile and the runner arrive as one matched set. You supply the drawer front, bottom, and back built to Blum's METABOX cutting dimensions.
On a 16 inch slide, 3/4 extension opens the drawer roughly 12 inches — enough to reach most of the interior, but the rear portion of the drawer stays inside the cabinet. If full access to the back of the drawer is essential, a full-extension slide is the right choice.
No. The motion technology on this kit is standard — the drawer closes mechanically, not with a soft-close damper. Blum's METABOX line includes soft-close variants; verify the specific SKU if damped closing is required.
The METABOX system is designed for frameless (European-style) cabinetry. Face-frame installations may require additional rear mounting brackets; confirm the mounting arrangement against Blum's METABOX installation documentation before cutting the drawer box.
The side profile stands 3-3/8 inches tall. This is the effective side height of the METABOX drawer box — factor it into the drawer opening height and the front design.
For shops and contractors building white-finish cabinetry who need a reliable steel drawer system at a practical price point, the METABOX 320M in White delivers matched components, solid capacity, and a finish that works with the interior rather than against it.
