This 18 inch Blum METABOX 320N drawer side and slide kit delivers a soft-closing, 3/4-extension drawer solution in White — a practical choice for cabinet interiors where a bright, coordinated look matters without adding cost. The kit pairs the steel drawer side with its matched runner so the box and the slide arrive as one system-engineered unit.
The METABOX 320N is Blum's economy single-wall drawer system, and that description is a feature, not a shortcoming. For painted kitchen cabinets, laundry rooms, bathroom vanities, and utility casework where the drawer interior shows but the budget does not call for a double-walled premium platform, the 320N hits the target. The White finish works directly against white or light-colored cabinet boxes — no liner, no cover, no finishing step needed on the sides. Shops running production kitchens in white or off-white use this system to keep the build moving without stopping to paint or wrap interior parts.
The 3/4 extension means the drawer opens to about 13 to 14 inches of travel on this 18 inch slide — enough to reach most of the drawer's contents. Buyers who need to retrieve items from the full rear of the box should look at full-extension options instead; this configuration is the right call when cost and interior appearance are the primary selection drivers.
The sides are formed steel, the standard material for the METABOX line, finished in White. The soft-close mechanism is integrated into the runner — not an add-on clip — so damped closing is part of the system rather than an aftermarket modification. The single-wall profile keeps the drawer side slim and the interior width maximized for the cabinet opening. Steel construction gives the side enough rigidity to hold 100 lb without flex across the 18 inch span.
Cabinet shops producing white-finish kitchens in volume will find this kit straightforward to install and easy to inventory alongside other METABOX 320N lengths. Designers specifying drawer hardware for painted or thermofoil kitchens benefit from the White side color matching the interior finish language without requiring an upcharge for premium box materials. Homeowners replacing drawer hardware in existing white-box cabinets get a system that disappears into the interior rather than contrasting with it. The 100 lb capacity covers the range of typical household loads — pots, utensils, tools — in a single SKU.
The METABOX 320N uses a damped soft-close mechanism integrated into the runner — it slows the drawer to a quiet stop rather than pulling it shut with a spring ramp. That is a meaningful distinction if you have been burned by self-close slides sold under the soft-close label.
At 3/4 extension, this 18 inch slide brings the drawer out approximately 13 to 14 inches. If you need to reach items at the very back of the box, a full-extension slide is the better choice. The 3/4 extension is appropriate for most everyday kitchen and utility drawers where back-of-drawer access is not a requirement.
The METABOX 320N mounts directly in frameless (32mm grid) cabinets. Face-frame installations require rear mounting brackets, which are sold separately and are specific to the METABOX system. Confirm you have the matching brackets before ordering for face-frame work.
The White finish is standard across the METABOX 320N line, so additional lengths and accessories ordered in White from the same series will match. METABOX components are not interchangeable with other Blum drawer platforms such as TANDEMBOX or LEGRABOX.
This is a drawer side and slide kit. Confirm the sold-as unit (single side member or complete pair) from the product listing before ordering, as METABOX components can be sold as individual members or as sets depending on the SKU.
The best interior hardware is the kind nobody notices — it matches the cabinet, closes quietly, and holds what you put in it. This White METABOX 320N kit does exactly that, making it a dependable daily workhorse for shops and homeowners who want the drawer to disappear into a white cabinet interior and just work.
