The METABOX 320H Drawer Side and Slide Kit in White pairs a 22 inch (550mm) single-wall steel runner with a 6 inch, 5-7/8 inch tall drawer side in a bright white finish. Designed for frameless cabinet construction, it gives painted and laminate interiors a finished, coordinated look without exposing raw steel or mismatched components.
The 3/4 extension on this kit opens the drawer to approximately three-quarters of its interior depth. That reach is sufficient for flatware drawers, spice and packet storage, shallow utility pulls, and most kitchen and bath base cabinet applications where the contents sit near the front. It is not a full-extension slide, so items stored at the very back of the drawer will require the user to reach in rather than having the drawer carry them fully to the cabinet face. If complete rear access is a design priority, choose a full-extension runner instead. For the majority of residential kitchen and bath drawer applications, 3/4 extension is the standard selection, and it is what this kit provides.
The white powder-coat finish on both the side profile and the runner makes this kit a natural fit for white-painted frameless cabinets, white laminate interiors, and any build where the drawer opening will be visible to the end user. When the drawer is pulled open, the side profile faces inward and the runner sits below; having both in white keeps the interior consistent rather than showing a gray or zinc runner against a white box. Steel construction ensures the finish is applied to a rigid substrate that holds its shape over long production runs. This is a single-wall profile, which is the METABOX format — a slim, economical side that integrates with the Blum METABOX system rather than adding a separate runner to a wood box.
The METABOX 320H is an economy-tier Blum drawer system aimed at production cabinet manufacturing rather than custom one-off builds. Shops running white frameless cabinets in volume — kitchen lines, bath vanities, closet systems — can spec this kit knowing the side and slide arrive as one coordinated unit in the correct finish. The soft-close behavior is built into the runner, so there is nothing extra to source or assemble before the drawer is complete. At 22 inches, this nominal length suits most standard 24-inch-deep base cabinet openings. The 100 lb capacity covers loaded kitchen drawers with confidence.
It is integrated into the runner mechanism. The SAP description notes the soft-close function as part of this kit; no separate add-on damper is needed for the slow-close behavior.
The drawer opens to approximately three-quarters of its total interior depth. Contents at the very back are not carried fully to the cabinet face. For most kitchen and bath drawers, 3/4 extension is the standard and adequate; if the application needs access all the way to the rear of the box, a full-extension runner is the right choice.
The METABOX system is engineered for frameless (European-style) cabinet construction. Face-frame installations require additional rear mounting brackets that are not included in this kit and are series-specific to METABOX. Confirm the bracket requirement before ordering for face-frame work.
The weight capacity listed is per pair of slides. One pair — one left and one right runner — supports up to 100 lb of drawer and contents combined.
No. METABOX front fixings, cover caps, and accessories are specific to the METABOX platform and are not interchangeable with TANDEMBOX, LEGRABOX, or MERIVOBOX components.
A matched side and slide in white means one fewer decision point on the production floor and a cleaner result inside the finished cabinet — exactly what a high-volume white kitchen or bath program needs from its drawer hardware.
