This is a 16 inch (400mm) Blum METABOX 320H drawer side and slide kit in White, built for cabinet shops and woodworkers who need a dependable, matched component set in a finish that stays cohesive inside white or light-toned cabinet interiors.
The 16 inch nominal length suits shallow-depth upper cabinets, desk pedestals, and compact utility drawers where a longer slide would overshoot the available depth. At 3/4 extension, the drawer opens enough for everyday access to most of its contents — a practical choice for drawers that see frequent use without requiring the full travel of an over-travel or full-extension system. The 100 lb capacity covers dense loads: a full set of flatware, a drawer of hand tools, or a stacked pantry pull-out all fall well within range.
This kit ships as a matched set of side profiles and running hardware, which means the side height, runner geometry, and finish are coordinated out of the box. That matters in production runs where mis-matched components slow assembly.
The METABOX 320H sides are formed steel finished in White, the same color family used across Blum's METABOX program. Inside a white melamine or thermofoil interior, the drawer box reads as part of the cabinet rather than a visible insert. Steel construction keeps the side profiles rigid under load without the thickness a wood drawer side requires, which preserves interior width in tight spaces. The Motion Technology on this kit is Standard — there is no soft-close damper or self-closing ramp on the runner itself. Closing behavior is determined by the drawer's weight and the cabinetry, not by an integrated mechanism.
Cabinet shops building production runs of white-interior kitchens or bath vanities use this kit where they want a consistent finish throughout without upgrading every drawer to soft-close hardware. Designers specifying shallow-depth cabinetry — islands with short back-to-front depth, office credenzas, or laundry room cabinets — get a slide length that actually fits the box. Homeowners replacing worn drawer hardware in existing white cabinetry find the White finish an easy match to factory interiors. The 100 lb capacity gives margin for drawers that carry heavier-than-expected loads over time.
The listing is a Drawer Side and Slide Kit — verify the sold-as unit with the product spec block to confirm whether the set completes one drawer or requires ordering multiples for a working pair.
A 3/4 extension slide opens the drawer to roughly 75 percent of its nominal length. The back portion of the drawer stays inside the cabinet when the drawer is fully open. Full extension brings the entire drawer to the cabinet face. If access to the back of the drawer is a priority, a full-extension slide is the right choice; 3/4 extension works well for drawers where contents sit toward the front.
No. The Motion Technology on this kit is Standard, meaning there is no integrated soft-close damper or self-closing ramp. The drawer closes under its own momentum. For damped closing, look for METABOX kits with BLUMOTION or a soft-close designation in the product name.
METABOX components are series-matched. Front fixings, backs, and accessories for the 320H series are specific to that series and side height. Do not mix 320H hardware with other METABOX or non-Blum runners.
The White METABOX 320H kit at 16 inches gives cabinet builders a finish-matched, capacity-rated drawer component that fits shallow cabinetry without compromise — keeping white-interior builds looking intentional from front to back.
