The Blum METABOX 330M is an 18 inch (450mm) drawer side and slide kit in White that pairs a steel side profile with an integrated soft-close, full-extension running mechanism. It is designed for shops and installers building painted or white-lacquered cabinetry where the drawer interior needs to match the surrounding finish without exposed hardware breaking the look.
The 330M is the right tool when the aesthetic requirement is as important as the mechanical one. White-lacquered kitchens, painted Shaker-style bath vanities, and built-in desk cabinetry all share the same problem: a silver or zinc runner pulls the eye as soon as the drawer opens. The White finish on these sides keeps the interior consistent. Full extension matters most in base drawers where pots, pantry stock, or file folders need to come fully forward — a 3/4-extension slide that stops short defeats the purpose of a deep pull-out. The 75 lb capacity handles the heaviest kitchen drawer loads a 18 inch box is likely to carry.
The side profiles are formed steel, finished in White to coordinate with painted box interiors and white cabinet liners. The soft-close damper is integrated into the runner rather than field-added, which keeps the mechanism consistent across every drawer in a run and eliminates the variability of retrofit dampers. At 3-3/8 inches tall, the profile suits standard drawer side heights without crowding a shallow box or looking undersized in a deeper one. The 450mm nominal length is the metric designation; all components in this kit are sized and designed to work together as one unit.
Cabinet shops building production runs of white-painted kitchen cabinetry reach for the 330M when a white interior is spec'd and soft-close is expected — which covers most residential kitchen projects today. Installers sourcing for a renovation where existing hardware is being replaced with a matching set will find the finish consistent with standard white drawer boxes. Designers specifying handle-less or minimalist kitchen programs benefit from the clean interior the White profile delivers. If the cabinet interior is a natural wood tone, stained finish, or gray, a different finish in this family is the better match.
The soft-close damper is integrated into the runner — it is part of the kit as delivered, not a field-added component. No separate damper purchase is needed.
Full extension means the drawer travels out to the cabinet face so the entire interior is accessible. It does not extend past the face — that would be over-travel, which is a different product class.
The 75 lb rating is per pair — both slides working together as installed on one drawer.
The profile is White steel, which coordinates well with white-painted or white-lacquered drawer boxes. For an exact finish match, compare a sample to your box material before committing to a full run.
This is a drawer side and slide kit — the steel side profile and running mechanism arrive together as one unit. You supply the drawer front, bottom panel, and back to complete the box.
When the finish inside the cabinet is white and soft-close is the standard on the job, the METABOX 330M in White delivers both without compromise — a drawer that opens fully, closes quietly, and keeps the interior looking as finished as the front.
