The Blum METABOX 320K drawer side and slide kit in White pairs a single-wall steel drawer side with an integrated runner, delivering a coordinated, factory-clean look inside white or light-painted cabinet boxes. Sold as a complete kit, this 16 inch (400mm) unit handles everyday kitchen, bath, and storage-drawer applications where a matched white interior matters.
The METABOX 320K is built for production cabinetry where a clean, coordinated interior is part of the specification. White is the natural choice when the cabinet box, doors, or drawer fronts are white or off-white — the side profile disappears into the interior rather than drawing the eye. Typical applications include painted kitchen base drawers, bath vanity drawers, laundry room cabinetry, and utility pulls-outs where a light interior is specified. The 16 inch nominal length suits standard 21-inch-deep base cabinets with room for the drawer front gap and required clearances per Blum's published cutting dimensions.
The 3/4 extension means the drawer opens to approximately three-quarters of its length — enough to reach everyday contents stored in the front two-thirds of the box. For drawers where full rear access to deep storage is required, a full-extension system would be the better fit. This kit suits cutlery, flatware, small utensil, and bath accessory drawers where items are typically stored shallow.
The side profile and integrated runner are steel, finished in White to match the METABOX program's coordinated interior aesthetic. The single-wall steel construction keeps the profile slim while providing the structural support for the 100 lb rated capacity. The self-closing mechanism is a ramp-and-spring close — a positive, definite engagement that draws the drawer shut — rather than a damped soft-close. Buyers who want a cushioned, silent close should select a METABOX or alternative system with an integrated soft-close damper instead. The White finish is consistent across the METABOX 320K program, so sides, runners, and other components ordered in White present a uniform interior.
Cabinet shops running white-interior kitchens and baths will find the METABOX 320K White a straightforward production choice: the kit format reduces component count per drawer, and the white finish ships ready to install without a painting step. Designers specifying painted cabinetry for residential or light commercial projects get a coordinated interior without sourcing drawer sides and slides from different programs. Contractors and renovators replacing worn drawer hardware in existing white cabinetry can match the interior color while gaining the Blum system's consistent motion and closing behavior. The kit is not suited to face-frame cabinets without confirming rear mounting bracket availability for this series, or to applications requiring full extension or soft-close damping.
No. The self-closing mechanism on this kit uses a ramp that pulls the drawer shut over the last inch of travel. It is a positive, spring-loaded close — not a damped soft-close. Soft-close uses a hydraulic damper to slow the drawer before contact; this system does not include one.
A 3/4 extension slide opens the drawer to roughly three-quarters of the slide's nominal length. On a 16 inch slide, that means approximately 12 inches of travel — enough to access the front portion of the drawer box, but not the full depth. If you need to reach items stored at the very back of a deep drawer, a full-extension system would serve you better.
No. The kit includes the steel drawer side and the integrated runner. The drawer front, bottom panel, and back are supplied by the builder to Blum's published cutting dimensions for the METABOX 320K series.
METABOX 320K is designed for frameless (European) cabinet construction. Face-frame installations may require rear mounting brackets that are series-specific — confirm bracket availability for this series before specifying it in a face-frame application.
Yes. The White finish is consistent across the METABOX 320K program, so components ordered in White from the same series present a uniform interior. Do not mix components from other METABOX series or other brands — METABOX accessories and parts are series-specific.
The METABOX 320K in White keeps production moving by delivering a matched side, runner, and finish in one kit — so the drawer box goes together cleanly and the interior looks intentional, not assembled from mismatched parts.
