The METABOX 320K Drawer Side and Slide Kit is Blum's economy metal drawer system, delivering a clean, factory-finished steel drawer box and integrated slide in a single coordinated package. This 14 inch (350mm) kit in White gives frameless cabinet builds a finished interior that matches the cabinet's color story without any additional painting or laminating.
The METABOX 320K fits best in frameless cabinet builds where a consistent white interior is part of the design spec. The White finish reads as a clean match inside painted or white-laminate boxes, making it a practical choice for kitchen base drawers, bathroom vanity pulls, and laundry room storage where the interior is visible when the drawer is open. The 14 inch nominal length targets shallower cabinets — think island base sections, peninsula knee drawers, and compact bath vanities — where a full-depth slide would overhang the available box depth. Because the drawer opens to 3/4 of its depth rather than full extension, it suits applications where contents sit toward the front of the drawer and full-back access is not a workflow requirement.
The drawer sides are formed steel finished in White, providing a rigid box wall that does not require a separate wood side. The steel construction keeps the drawer box light while standing up to the daily loading and unloading of kitchen or bath contents. The self-closing function is a mechanical ramp built into the runner — as the drawer is pushed to within the last inch of closing, the ramp pulls it home positively. This is a Standard motion system: there is no damping mechanism, so the close is firm and audible rather than the silent glide of a damped soft-close. Buyers who need a damped close should look at Blum's METABOX with BLUMOTION or one of the TANDEMBOX platforms instead.
Cabinet shops running white kitchen or bath programs find the METABOX 320K in White a straightforward economy drawer for secondary and auxiliary drawers — utensil pulls, bath accessory drawers, and laundry supply storage where a premium metal drawer system would be cost-prohibitive. Designers specifying a white-interior cabinet line use it to keep the drawer interior color consistent without custom finishing. Contractors building out production renovations value the integrated side-and-slide format because it reduces the parts count on the job: one kit per drawer rather than a separate slide order and a separate box material order.
No. The self-closing ramp pulls the drawer shut mechanically over the final inch — it is a positive, audible close, not a damped soft-close. If damped closing is required, choose a METABOX with BLUMOTION or a TANDEMBOX system.
METABOX 320K is designed for frameless (European-style) cabinet construction. Face-frame installs require rear mounting brackets, which are not included in this kit and must be ordered separately.
This is a 3/4 extension slide, so the drawer opens to roughly three-quarters of the 14 inch nominal length — not the full depth. If you need full access to the back of the drawer, a full-extension slide is the right choice.
The 100 lb rating is per pair of slides. Check the source data for dynamic versus static specifics; for everyday kitchen and bath drawer loads this capacity is more than sufficient.
The kit contains the steel drawer sides and integrated slide runners. The drawer bottom and back panel are not included; build those to Blum's published cutting formula for METABOX 320K.
For production cabinet builds where the interior finish matters and the budget calls for an economy system, the METABOX 320K in White delivers the box and the runner in one package — no extra painting, no mismatched hardware, and no separate slide order to manage alongside the drawer box material.
