Brassera model BRS-KNB-ZNC-005 introduces a square flat-plate cabinet knob developed for contemporary residential millwork. Zinc alloy construction establishes clean geometric lines across modern furniture frontages without unnecessary ornament. Cabinetmakers specify this square cabinet knob family to bring crisp definition across residential casework. Standard factory production provides two finish selections: Matt Black plus Brush Nickel. These metallic tones coordinate across kitchen, bedroom, plus living area cabinetry. One order covers a whole run of doors and drawers.

A Flat Square Plate on a Cylindrical Stem
Each knob centers on a plain flat square top plate finished with gently rounded outer corners. Beneath this square plate, a short straight cylindrical stem descends toward mounting panel faces. Product photography shows a visible ring where stem meets plate, marking the transition between square geometry and round stem proportions. Vertical clearance behind plate edges gives fingers comfortable room during daily opening routines. The plate corners roll over gently rather than meeting at sharp points.
Thirty Millimeters Across, Twenty-Two High
Official dimension card documentation declares a square top plate measuring 30 mm by 30 mm across outer edges. Overall height reaches 22 mm from the cylindrical base to the top plate face. Declared piece weight is about 32.6 g per individual knob. Zinc alloy composition resists rust across moisture-exposed residential environments inside kitchen or bathroom spaces. Balanced proportions deliver understated visual presence across varied cabinet frontages. The 22 mm height sits close to the face, keeping drawers clear of neighbouring panels.
Brush Nickel and Matt Black Pairings
Visual inspection of product photography highlights two factory color options suited to varied joinery palettes. Brush Nickel exhibits a soft brushed sheen with muted directional reflections, delivering balanced silver tone across light oak, painted cabinets, or stone surfaces. Matt Black provides non-reflective dark coloration, creating striking graphic contrast over pale timber drawer fronts or white cupboards. Installers choose nickel cabinet knob fittings for understated metallic warmth, while black cabinet knob hardware adds bold linear accents across modern woodwork.
A Threaded Socket in the Stem Base
Underside views show a threaded mounting socket centered within the cylindrical stem base metal. Single-hole fitting allows straightforward alignment through casework door leaves or drawer fronts. A bolt passes from the rear of the panel into the socket. Straight stem positioning keeps square top plates parallel to surrounding panel margins. The socket sits centered in the stem base, as the underside view shows.
Joinery specialists install these square flat knobs across cabinets, drawers, dressers, wardrobes, cupboards, plus wine cabinets. Room applications cover kitchen casework, bathroom storage units, bedroom furniture, living room cupboards, dining room storage, kids room pieces, plus apartment joinery. Square top faces keep one consistent profile across varied residential storage openings, harmonizing with both horizontal and vertical casework layouts. Rounded corners soften each plate edge without changing the square outline.
