204 Invisible Light Duty 180˚ Opening Hinge, Satin Brass

Soss 204 Invisible Hinge For Concealed Swinging

Soss 204 invisible hinge gives a clean, concealed pivot for light duty applications, so doors or panels swing without exposed hinge butts changing the finished look. The hinge is fully anchored in a deep mortise, which seats the body solidly into the edge of the door and frame for a tight, aligned fit. Hinges are made of laminated links, and this internal link construction controls the hinge movement through the full swing, helping the leafs track smoothly with minimal play. The hinge is made of zinc die cast with steel links, combining a rigid body with tougher steel link arms that carry the motion under load. This 204 invisible light duty hinge has 180 degree opening capacity, allowing the door or panel to open flat against the adjacent surface for clear access through the opening in everyday use.

Key Details That Support Clean Installations

• The hinge is fully anchored in a deep mortise, so once the pocket is machined to the hinge outline, the body nests into the edge and keeps the pivot line fixed for repeatable alignment between door and jamb.
• Hinges are made of laminated links, meaning the moving elements are stacked plates rather than loose knuckles, which guides the opening path consistently and reduces side play over the swing of the door.
• The hinge is made of zinc die cast with steel links, so the zinc body provides a stable mounting shell while the steel links handle the repetitive pivoting motion in service.
• This 204 invisible light duty hinge has 180 degree opening capacity, which lets doors open all the way back, keeping the door out of the opening when full access to the cabinet or passage is needed.
• The satin brass finish, described as dull brass, presents a muted brass tone at the hinge edge where it is visible, allowing the hardware color to coordinate with brass-themed projects.

Deep Mortise Invisible Hinge Mounting Behavior

The hinge is fully anchored in a deep mortise, so the installation revolves around cutting a recess that matches the hinge body depth and outline in both the door and frame edges. This deep pocket seating pulls the hinge into the material, so the pivot hardware sits flush and leaves only a narrow joint line, supporting a concealed look on both faces of the door. Because hinges are made of laminated links, the pivot action remains inside the mortised body, so once the hinge is set at the correct depth, the moving parts stay within the edge profile while opening and closing. The 180 degree opening capacity means the hinge geometry is designed so the door clears the jamb and then folds back to a flat position, which is useful wherever full swing is needed without trim interference.

Using The 204 Invisible Hinge In Real Projects

Where The 204 Invisible Hinge Is Typically Applied

The 204 invisible light duty 180 degree opening hinge, in satin brass, suits projects where a conventional hinge butt is not needed, such as flush doors, panels, or cabinet work that calls for concealed hardware. The product is categorized under invisible hinges and invisible and recessed hinges, so its role is to sit in a routed mortise and keep the hinge mechanism hidden between the door and frame. Because the hinge is made of zinc die cast with steel links, it aligns with light duty applications where the core need is a smooth concealed pivot and a neat edge presentation rather than a surface-mounted hinge leaf.

Why The Laminated Link Design Supports Consistency

Hinges are made of laminated links, and these stacked steel link plates form the moving core of the Soss 204 invisible hinge, guiding the swing in a controlled arc. The laminated link construction keeps the motion guided inside the mortised body, so once the hinge is set square in the recess, the door tracks the same way every time it is opened or closed. The hinge is fully anchored in a deep mortise, which locates the pivot line at a fixed distance from the door face, helping maintain uniform reveals along the edge of the door. The 180 degree opening capacity reflects the internal geometry of these links, allowing the door to travel fully open without the leaves binding against the mortised edges.
