Soss 218US14 Heavy Duty Invisible Hinge Bright Nickel

Product Description

The SOSS 218US14 is a heavy-duty invisible hinge designed for interior and exterior doors requiring a concealed hardware solution. When the door is closed, the hinge body is completely hidden within the door edge and frame, leaving a clean, uninterrupted surface. This model is sized for 1.75-inch thick doors, with a leaf face measuring approximately 1.125 inches wide by 4.625 inches long. The bright nickel finish provides corrosion resistance and a polished appearance suitable for both residential and light commercial applications. Finish carpenters, millwork installers, and door hardware specialists are the primary trades that work with this product.

The 218US14 is suited for interior passage doors, entry doors, and cabinetry applications where a traditional surface-mounted or mortise hinge would interrupt the visual line of the door and frame. The concealed barrel mechanism engages only when the door swings, keeping all hinge components recessed when closed. This makes the hinge a common choice in architectural millwork, high-end residential builds, and commercial interior door installations where clean sightlines are specified.

Installation Notes

Installation requires precise mortise routing into both the door edge and the door frame jamb — a router with a hinge template is standard practice. Verify door thickness and hinge mortise dimensions before cutting. This product should be installed by an experienced finish carpenter or door hardware installer familiar with concealed hinge systems. Always follow local building codes for door hardware requirements on egress or fire-rated assemblies.
