Soss 205US4 Invisible Hinge Metal Doors Satin Brass

Product Description

The SOSS 205US4 is a light-duty invisible hinge designed for metal doors in residential and light commercial applications. When installed, the hinge sits fully concealed within mortised pockets in the door and frame, leaving no exposed hardware on the face of the door. The hinge measures 0.5 inches by 2.375 inches and ships as a pair. Finished in satin brass, it suits interior doors where a clean, hardware-free appearance is required. Licensed contractors and finish carpenters install this type of hinge when the project calls for a seamless aesthetic without sacrificing reliable door operation.

The 205US4 is suited for light-duty metal door installations in interior settings such as offices, hospitality spaces, and residential interiors. It is mortised into both the door edge and the door frame, requiring precise routing or milling for a flush fit. The satin brass finish coordinates with complementary hardware on interior metal door assemblies. This hinge is sold as a pair, making it appropriate for single-door applications where two hinge points are standard.

Installation Notes

Installation requires precise mortise routing in both the door edge and the door frame to achieve a flush, concealed fit — use a router with a sharp straight bit and a hinge template for accurate results. Remove the door from its opening and ensure the frame is plumb and square before laying out hinge locations. Follow the door manufacturer's recommended hinge placement spacing and local building codes for door hardware. Do not over-torque mounting fasteners, as metal door skins can deform under excessive clamping force.
