This is a complete 20 inch LEGRABOX F Height drawer system from Blum in Silk White Matte, built for deep storage applications that demand a tall side profile, full-extension travel, and integrated BLUMOTION soft-close. The F Height side at 241mm (9-1/2 inches) tall suits pots drawers, pantry pull-outs, tall file drawers, and other large-capacity applications where a standard-height box simply runs out of wall.
The F Height profile exists for drawers where the contents dictate a tall box wall. A pots-and-pans drawer benefits from sides that contain tall stockpots without a gallery rail doing the work. A pantry pull-out with tall jars and bottles stays organized behind a side wall that actually clears the containers. A deep filing drawer gains the interior height to carry hanging folders with tabs riding well above the rail. In each case, the 241mm side height is doing structural and organizational work that a lower profile cannot replicate. Full-extension travel means the drawer comes all the way out — every pot, every jar, every folder is reachable without reaching blind into the back.
LEGRABOX sides are double-walled steel — two formed walls with a hollow core that hide every fastener and present a smooth surface inside and out. The result is a side profile that is slim in visual weight but structurally rigid under a 170 lb load. Silk White Matte is a flat, non-reflective white that reads as a neutral in cabinets finished in painted white, soft white lacquer, or white-laminate interiors. It also coordinates with AMBIA-LINE organization inserts offered in the LEGRABOX program. The finish holds the drawer's look over years of daily use without showing the scuffs that a gloss surface would accumulate.
Cabinet shops building production kitchens with dedicated deep-storage drawer banks reach for F Height when a client wants maximum vertical capacity in the box itself rather than relying on dividers and rails to compensate for a shorter side. Designers specifying handle-less kitchens pair this system's BLUMOTION close with Blum's TIP-ON or SERVO-DRIVE opening systems for a fully integrated handle-free experience. Contractors retrofitting older cabinetry with modern drawer systems choose F Height when the existing opening is tall enough to justify the profile and the contents warrant the 170 lb capacity. The Silk White Matte finish is the natural call when the cabinet interior is white and the goal is a seamless, factory-fitted appearance with no visible color break between box and cabinet wall.
The system ships as a complete set — steel double-walled side profiles, integrated runners, and associated hardware. You supply the drawer front, the bottom panel cut to Blum's formula for a 500mm nominal length system, and the back panel. Build the box to Blum's published specification for F Height before installation.
No. BLUMOTION is a damped soft-close mechanism built into the runner. It decelerates the drawer at the end of travel and settles it silently. A self-closing ramp pulls the drawer shut mechanically — that is a different and less refined motion. This system is soft-close only.
TIP-ON BLUMOTION units are a Blum combined system that integrates push-to-open ejection with BLUMOTION damping. This slide already has BLUMOTION built in, so adding plain TIP-ON hardware would work against the soft-close mechanism. If handle-less opening is the goal, specify TIP-ON BLUMOTION as the combined system rather than adding push-to-open hardware separately.
Yes. AMBIA-LINE is Blum's interior organization line for LEGRABOX drawers. Inserts, dividers, and frames from the AMBIA-LINE program are designed to work within the LEGRABOX interior — select AMBIA-LINE components sized to a 500mm nominal length drawer. Do not use ORGA-LINE components, which are made for TANDEMBOX, not LEGRABOX.
LEGRABOX systems mount directly to frameless (face-frame-free) cabinet boxes on the 32mm grid. Face-frame cabinet installations require the appropriate rear mounting brackets and face-frame adapter hardware, sold separately. Confirm cabinet construction before ordering.
The F Height LEGRABOX in Silk White Matte brings 170 lb capacity, full-extension travel, and BLUMOTION damping to the drawers where contents are heaviest and access needs to be complete. The flat white finish makes the box part of the cabinet rather than a contrast against it — the hardware does the work while the look stays quiet.
