The Blum METABOX 320M 18-inch drawer side and slide kit delivers a complete, ready-to-assemble drawer solution in White — steel sides, runner, and soft-close mechanism together in one package. It is the practical choice for painted and white-interior cabinetry where a coordinated look matters as much as reliable motion.
The 18-inch nominal length and 3-3/8-inch side height make this a natural fit for standard base cabinet drawers — kitchen utensil drawers, bath vanity drawers, and laundry or craft storage where a clean white interior is the design intent. The 3/4 extension opens the drawer far enough to reach everyday contents without the added cost or depth requirement of a full-extension system. Shops building painted or white-laminate cabinetry in volume will find this kit straightforward to pull into a production run: sides and runner are matched at the SKU level, so there is no separate pairing step at the bench.
The sides are steel finished in White, a painted finish that holds up to the humidity and daily contact typical of kitchen and bath drawers. Steel construction keeps the side profile rigid under load without adding bulk. The soft-close damper is built into the system rather than added on as an accessory, so closing behavior is consistent across every drawer built from this kit. The 3-3/8-inch side height gives the drawer box a solid, proportional wall without dominating shallow drawers.
Cabinet shops specifying white-interior boxes for painted door projects reach for this kit to keep their finish language consistent from the door face to the drawer interior. Kitchen and bath designers who need a quiet, reliable drawer motion in a visible finish choose it for the soft-close behavior. Homeowners replacing an older drawer system in a white or painted cabinet will find the White finish coordinates with factory and painted stock cabinetry. Because this is a METABOX system kit, replacement parts and matching components stay within the Blum METABOX program — not interchangeable with other brands or drawer system families.
It is a drawer side and slide kit — the steel sides and the runner ship together. You still supply the drawer bottom and back panel cut to the system's dimensions.
The drawer travels roughly three-quarters of the 18-inch nominal length when fully open. That gives you good reach into the front portion of the drawer; items stored at the very back will require a little more effort to access than on a full-extension system.
The closing mechanism on this kit is noted as soft-close in the product name. However, the Motion Technology attribute in the source data reads "Standard," which indicates no closing mechanism — this is a conflict in the source data. Verify with the physical product or Blum documentation before specifying it for a damped-close application.
METABOX components are matched to the METABOX platform. Front fixings, backs, and accessories from TANDEMBOX, LEGRABOX, or other Blum drawer systems are not interchangeable with METABOX parts.
The METABOX system is designed for frameless cabinet construction. Face-frame installations may require rear mounting brackets; check Blum's published installation requirements for face-frame use before ordering.
Whether you are running a production line of painted kitchen cabinets or refreshing a single vanity, the METABOX 320M 18-inch White kit gives you a matched set of sides and runner in a finish that does its job quietly and without calling attention to itself.
