212 Medium-Duty Invisible 180˚ Opening Hinge, Satin Brass

212 Medium-Duty Invisible Hinge For Clean Joints

212 medium-duty invisible hinge describes a Soss invisible hinge built so the hinge disappears into the edge of the workpiece, which keeps door and panel lines visually clean on finished jobs. The hinge belongs to the invisible hinges product class, so it is designed to sit concealed in a routed pocket rather than on the surface. The hinge uses laminated links in its construction, which lets the knuckles fold tightly into the mortise so the hinge operates without a visible barrel. The hinge is made for use when a hinge butt is not needed, giving you a way to hang doors and panels without traditional butt hinge outlines. Its satin brass finish presents a dull brass look, which coordinates with other satin brass fittings when you want a consistent hardware tone across the room.

Key Soss Invisible Hinge Details For Pros

• The hinge is made of laminated links, which creates a compact joint that folds smoothly into the mortise so movement stays controlled even on medium-duty applications.
• The hinge is fully anchored in a deep mortise, which sets the body into solid material so loads transfer into the door and frame instead of pulling on the surface edge.
• The hinge is made of zinc die cast material with steel links, so the body and moving parts pair cast stability with steel link strength where the joint articulates under use.
• The hinge has 180 degree opening capacity, which lets doors or panels swing back flat against adjacent surfaces, improving access in cabinets, casework, or similar openings.
• The product is described as a Soss hinge in dull brass, so the finish presents as satin brass that blends with other satin brass components on doors, panels, or cabinetry.

Deep Mortise Invisible Hinge Mounting Behavior

This Soss invisible hinge is fully anchored in a deep mortise, so the installer removes material from both the door and the frame and seats the hinge body within those cavities. Mounting the hinge in this way pulls the pivot point inside the thickness of the material, which supports tight reveals along the edge because there is no surface-mounted leaf projecting outward. The laminated links operate within the mortise when the door moves, which keeps the motion contained inside the cutout and preserves a flush exterior face. The 180 degree opening capacity means the mounted door can move from fully closed to fully open in a wide arc, which supports layouts where the door needs to rest flat against an adjacent run or cabinet side.

How This Soss Invisible Hinge Works In Use

Invisible Hinge For Doors, Panels, And Casework

This Soss invisible hinge sits in the hinges, invisible and recessed hinges category, so it is suited to jobs where the hardware needs to be concealed in wood or similar materials rather than sitting on the surface. Being an invisible hinge means that once the door or panel is closed, the hinge body and laminated links are recessed inside the deep mortise and do not show on the face, which supports clean architectural or cabinet lines. The hinge is described as medium-duty, which points to use on doors, panels, or cabinet components that see regular operation but do not require heavy-gate hardware. Its 180 degree opening capacity lets those installed components swing through a full open arc, which is useful on cabinets, closets, or passage-style panels where full access to the opening is needed during use.

Laminated Links And Deep Mortise For Consistent Results

The hinge is made of laminated links, and those links fold in sequence as the door moves, which keeps the pivot motion controlled inside the mortise and helps the door track consistently along its swing path. The body is made of zinc die cast with steel links, which combines a rigid cast housing for the mortise pocket with steel at the moving joints where wear is concentrated, supporting long-term motion in normal woodworking environments. Because the hinge is fully anchored in a deep mortise, the load is carried by the surrounding material rather than by surface screws alone, which supports firm alignment of the door edge relative to the frame over time. The satin brass, or dull brass, finish designates the visible portions of the hinge as brass toned, which helps the project maintain a coordinated appearance wherever the hinge edges are visible in the open position.
