The Sugatsune 304B-C46/14 is a concealed self-close hinge for 9/16-inch overlay doors on face-frame or frameless cabinets, built from stainless steel for lasting corrosion resistance in demanding environments.
Stainless steel is the right call when the environment pushes back: commercial kitchens, spa and bath cabinetry, marine environments, outdoor-adjacent utility spaces, and any setting where humidity or cleaning chemicals are part of daily life. The 304B series brings that material choice into a standard concealed hinge format, so the benefits of stainless extend to the door hardware without changing how the installation works. The 35mm cup bores into the back of the door, the arm connects to a Sugatsune base plate mounted to the cabinet, and the self-close spring handles the last few degrees so the door closes on its own. The plate is a separate purchase matched to the Sugatsune 304B series.
The hinge is stainless steel throughout, not a plated or coated finish over a base metal. That distinction matters in moisture-heavy applications where a surface coating would eventually breach and corrode. The straight arm carries the 9/16-inch overlay geometry, and the screw-on connection anchors it firmly to the cabinet side or frame. With a weight rating of 11 lb per pair, this hinge is sized for standard light-to-medium cabinet doors within that range.
This hinge fits builders and specifiers who need the clean, hidden look of a concealed Euro hinge in a material that holds up where nickel-plated steel would not. It suits both frameless and face-frame boxes, making it a consistent spec across a mixed project. The screw-on mount is the right choice where a tool-free clip plate is not required and a direct mechanical fastening is preferred. Doors in the standard 16 to 22mm thickness range are the target; for thicker doors, a thick-door variant is needed. Because this is a Sugatsune product, plate compatibility is specific to the 304B series and should not be assumed for other brands.
No. The hinge attaches to a base plate that mounts to the cabinet, and the plate is sold separately. Use a Sugatsune plate matched to the 304B series and your cabinet construction.
The hinge is stainless steel construction, not a plated coating over another metal. That is what makes it the right choice for high-humidity and corrosion-risk environments.
Self-close uses a spring to pull the door shut over the last few degrees of travel. Soft-close uses a damper to slow the door so it does not slam. This hinge is self-close: the spring pulls it shut, without cushioning the final contact.
No. Mounting plates are brand and series specific. This hinge requires a Sugatsune 304B-compatible plate. Plates from Blum, Grass, Salice, Hettich, or other brands will not connect correctly.
Specify the 304B when the project demands a concealed hinge that holds up in hard conditions, closes reliably on its own, and disappears behind the door when closed.
