The Sugatsune 304B-46/14 is a concealed long arm European hinge machined from 304 stainless steel, designed for face-frame and frameless cabinets in environments where corrosion resistance matters. It swings free with no spring and no damper, making it the right pick for push-to-open systems and any application where controlled door movement is needed.
Free-swinging means no spring and no damper. The door stays open where you leave it and stays closed only with a catch or magnet. That makes this hinge the natural fit for push-to-open systems, where a self-close spring would work against the release mechanism. It also suits ADA-compliant cabinetry and any setup where the installer or designer wants to control door movement through a dedicated device rather than the hinge itself.
The 304 stainless body takes this further. Marine kitchens, pool house cabinetry, commercial food-service casework, and coastal bath installations all put hardware through conditions that corrode plated steel over time. The 35mm cup bores into the door in the standard way, and the arm mounts to a separate base plate on the cabinet, ordered separately. The 43mm boring pattern is specific to this series, so confirm that spacing before ordering replacement hinges or plates.
304 stainless steel resists rust and oxidation without a surface coating to chip, flake, or wear through. The finish reads as a clean brushed stainless, consistent with the industrial and commercial aesthetic that often accompanies this material choice. Because there is no plating layer, the corrosion resistance is intrinsic to the alloy, not dependent on a finish film staying intact. The 11 lb weight rating per pair is a design parameter for the door weight this hinge is engineered to carry, so size door weight and hinge count against the manufacturer's load guidance.
Cabinet shops specifying marine, hospitality, or food-service work will recognize 304 stainless as the baseline corrosion-resistant alloy for those environments. Designers putting together handle-less fronts with push-to-open hardware need a free-swinging hinge to pair with the release mechanism. Contractors working in coastal regions where salt air shortens the life of plated hardware will find this a straightforward material upgrade. It installs on either face-frame or frameless boxes, so it does not require a separate SKU for different cabinet types on the same job.
No. A free-swinging hinge has no spring or damper, so the door does not pull itself shut. A magnetic catch or push-to-open mechanism is needed to keep the door closed.
Yes. The hinge arm connects to a base plate that mounts to the cabinet, and the plate is a separate purchase. Use a plate matched to the Sugatsune 304B series and your cabinet construction type.
This hinge uses a 43mm boring pattern, which differs from the 45mm spacing common on other European concealed hinges. Confirm the spacing before ordering plates or when replacing existing hardware so the holes line up correctly.
A soft-close adapter can be added to some free-swinging hinges as a separate component. Check Sugatsune's accessory line for a compatible add-on damper for the 304B series before specifying one.
Specify this hinge when the job calls for a free-swinging concealed hinge that will not corrode in demanding environments, and where the door's closing behavior is managed by the hardware it pairs with rather than the hinge itself.
