This 18 inch LEGRABOX F Height drawer system from Blum pairs a clean Silk White Matte finish with the platform's tallest standard side profile, integrated BLUMOTION soft-close, and a 170 lb weight capacity — delivered as a complete system ready for installation in frameless cabinetry.
The F Height profile is the right choice when contents are tall, heavy, or both. A 241mm (9-1/2 inch) side handles a full row of canned goods standing upright, a stack of sheet pans, or a collection of cast-iron cookware — loads that shorter profiles simply cannot contain. Full extension means nothing hides at the back: the entire drawer interior clears the cabinet face so a user can reach or see every item without leaning in. The 18 inch nominal length suits standard base cabinet depths commonly found in kitchen, laundry, and pantry runs, as well as workshop storage and office credenzas where deep drawer access matters.
Silk White Matte is a deliberate finish choice, not a default. In kitchens with white or off-white cabinet boxes, the matte surface reads as part of the cabinet rather than as added hardware. It avoids the contrast that a gray or metallic interior creates against a white painted front, so the transition from box to front stays visually quiet. The steel double-walled sides carry this finish on both the inner and outer face, so the interior looks consistent whether the drawer is open or closed. LEGRABOX sides are compatible with Blum's AMBIA-LINE interior organization inserts, which are also offered in finishes that coordinate with the Silk White platform.
Cabinet shops running white-interior production kitchens will find the Silk White Matte finish eliminates a finishing step — the box arrives ready to pair with painted or thermofoil fronts. Designers specifying seamless handle-less kitchens can combine this system with Blum's TIP-ON BLUMOTION push-to-open unit to keep the front panel clean. Contractors retrofitting existing frameless cabinets can match an existing white interior without repainting or relining the box. The 170 lb capacity also opens the system to non-kitchen applications: shop storage, AV credenzas, and office filing furniture where a white interior box is the design requirement and load demands are real.
It is a complete drawer system. The LEGRABOX set includes the side profiles with integrated runners, the steel back, and front fixings — you supply the bottom panel and drawer front, cut to Blum's published dimensions for this nominal length and height.
LEGRABOX mounts directly to the cabinet side wall on the 32mm grid, which is standard frameless (full-access) construction. Face-frame cabinet installations require rear mounting brackets, which are sold separately and are series-specific to LEGRABOX.
AMBIA-LINE is the interior organization line made for LEGRABOX drawers, offered in Orion Gray Matte and stainless steel finishes. Confirm the finish pairing you want before ordering inserts, as the two AMBIA-LINE finishes do not match Silk White identically.
Yes — but not with a plain TIP-ON unit. Use TIP-ON BLUMOTION, Blum's combined push-to-open and soft-close unit, which replaces the standard BLUMOTION damper. A plain mechanical TIP-ON unit conflicts with the integrated soft-close and should not be combined with it.
LEGRABOX drawer boxes are built to Blum's published cutting formula for the nominal length and side height; the bottom panel thickness and groove position are specified in that document. Follow the Blum cutting dimension guide for the 18 inch (450mm) F Height system before cutting your bottom panel.
The Silk White Matte LEGRABOX F Height system brings a clean finish and a 170 lb capacity to the same drawer — a combination that handles production kitchen builds, heavy-duty pantry pull-outs, and design-forward cabinetry where the interior finish is part of the specification.
