This 22 inch LEGRABOX F height complete drawer system from Blum brings a 241mm (9-1/2 inch) double-walled steel side profile in Silk White Matte together with integrated BLUMOTION soft-close and a 170 lb weight capacity. It is a finished, engineered platform — sides, runners, and closing mechanism arrive as one system — sized for deep pot drawers, pantry pull-outs, and tall-front kitchen applications where both interior volume and a clean white finish matter.
The F height profile is LEGRABOX's tallest standard side. Paired with a 22 inch nominal length, this system is the natural choice for base cabinet pot drawers, deep pantry pull-outs stacked with canned goods, and any application where a taller front is specified to cover more of the cabinet face. The full-extension runner means nothing sits stranded at the back — the whole drawer comes out to the opening.
The Silk White Matte finish earns its place in kitchens where white or light-toned interiors are part of the design intent. A matte surface reads quietly beside painted or thermofoil fronts, and the double-walled steel construction keeps the interior face smooth and clean-looking without exposed fasteners. Designers specifying white-on-white interiors get a system that supports the look rather than interrupting it.
LEGRABOX sides are formed steel with a double-walled profile: an inner and outer wall in one extrusion, hiding the fasteners and presenting a finished surface on both faces. The Silk White Matte coating is applied at the factory, so the color is consistent through the production run and matches other LEGRABOX components ordered in the same finish.
BLUMOTION is Blum's integrated soft-close damper. On this system it is built into the runner rather than added as a clip-on accessory, which keeps the closing behavior consistent across the drawer's load range. The mechanism slows the drawer through the last portion of travel and settles it closed quietly — relevant in kitchens where heavy pots are being loaded and slammed drawers are a daily complaint.
Cabinet shops running white or off-white kitchen programs find the Silk White Matte side a cleaner match for painted interiors than a gray or steel finish. Kitchen designers specifying handle-less or integrated-front cabinetry use the F height's tall profile to support the proportions of a full-height drawer front. Contractors on production kitchen builds value the 170 lb rating as coverage for the heavy-use drawers — the ones that actually take the daily load of a working kitchen — without needing a separate heavy-duty slide solution.
This system suits frameless cabinet construction; the runners mount directly to the cabinet side on the 32mm grid. For face-frame installations, add the appropriate rear mounting brackets, which are sold separately and are series-specific to LEGRABOX.
The system includes the double-walled steel sides, integrated runners, and BLUMOTION soft-close mechanism. You supply the drawer front, the bottom panel (cut to the system's formula), and the back panel. Front fixing brackets are also sold separately and must be matched to the LEGRABOX F height.
170 lb is the system rating per pair — both runners working together. The LEGRABOX heavy-duty series carries a 170 lb static rating, which suits loaded pantry pull-outs and pot drawers in normal kitchen use.
Yes, but face-frame installations require rear mounting brackets that are not included. Those brackets are LEGRABOX-specific and sold separately — confirm the bracket for F height when ordering.
Yes. AMBIA-LINE is Blum's interior organization line built for LEGRABOX drawers. The F height's interior volume is well suited to AMBIA-LINE's deeper inserts. Select AMBIA-LINE components by nominal length (550mm for this system) and confirm the insert height clears the F height profile.
Silk White Matte is a standard LEGRABOX finish, so front fixing brackets, cover caps, and gallery rails ordered in the same finish from the LEGRABOX program will match. Components from other Blum platforms — TANDEMBOX, MERIVOBOX — are not finish-matched and should not be mixed.
The LEGRABOX F height in Silk White Matte handles the heaviest drawers in the kitchen and stays visually quiet doing it — a system that supports the cabinetry design rather than competing with it.
