This is a complete 16-inch LEGRABOX drawer system in K height from Blum, finished in Orion Gray Matte. It brings together the steel side profiles, integrated BLUMOTION soft-close runners, and the platform's engineered components in one system sized for mid-depth cabinet pulls with a 5-1/16-inch side height. It is designed for kitchen, bath, and furniture cabinetry where a coordinated interior finish matters as much as the hardware that moves it.
Orion Gray Matte is the interior color specification most specified alongside dark cabinet doors, matte black hardware, and charcoal or graphite door panels. Because the LEGRABOX side profile is the visible wall of the drawer interior, its color reads every time the drawer opens. In a two-tone kitchen with white uppers and dark lowers, gray interior boxes maintain a deliberate palette rather than breaking it with a bright white or a reflective steel surface. The matte texture also reduces the contrast between the drawer interior and the front panel finish, so the overall look reads as intentional from countertop to cabinet toe.
The LEGRABOX side profiles are formed steel in a double-walled configuration: two steel faces with a hollow core that hides fasteners and presents a clean surface inside and out. The running gear is integrated into the platform, not added on, so the side profile and the runner work as one piece rather than as a slide mounted to a wood box. At this nominal length, the system is rated for 125 lb of dynamic load, with BLUMOTION damping tuned to handle that range without adjustment. The Orion Gray Matte powder coat is consistent across the LEGRABOX program, so the color matches across drawers of different heights in the same kitchen run.
Cabinet shops running frameless production kitchens reach for LEGRABOX K height when the project calls for a mid-profile drawer that clears the cabinet interior without cutting into pull-out storage above. Designers specify the Orion Gray Matte version when the door specification and interior finish need to share a palette rather than contrast. Renovation contractors replacing dated slides in an existing frameless cabinet often choose this system because the side profile, runner, and front fixing arrive as one engineered package with a published cutting formula for the bottom and back. The 16-inch nominal length covers the most common base cabinet depth in North American kitchens.
K is Blum's designation for a 128.5mm (5-1/16 inch) side profile height. It sits between the low-profile M height and the taller F height, making it the standard choice for typical base cabinet drawer pulls without a gallery rail.
Yes. Blum applies Orion Gray Matte consistently across the LEGRABOX program, so a K-height box and an F-height box in the same kitchen will match in color and texture.
This system includes the side profiles and integrated runners. You will also need front fixing brackets (sold separately, matched to LEGRABOX K height), a bottom panel cut to Blum's published formula, and a back panel. AMBIA-LINE organization inserts are available separately if the project requires an organized interior.
LEGRABOX is engineered for frameless (32mm system) cabinet construction. Face-frame installations require Blum's face-frame adapter bracket set, which is sold separately and must be specified for this platform.
The 125 lb rating is a dynamic load figure for the system at this nominal length. It reflects the working capacity under normal use, not a static shelf load. For standard kitchen drawers, 125 lb is well above what pots, dishes, and pantry contents will demand.
The LEGRABOX K height in Orion Gray Matte delivers the side profile, runners, and BLUMOTION soft-close in one engineered package at a nominal length that fits the majority of base cabinet depths. For shops and designers who specify finish as carefully as motion, it keeps the interior of the drawer box on-palette from the first open to the thousandth.
