Soss 212SSUS32D Invisible Hinge Satin Stainless Steel

Product Description

The SOSS 212SSUS32D is a medium-duty invisible hinge designed to mount completely concealed within the door and frame, leaving no exposed hardware when the door is closed. Finished in satin stainless steel, it is built for 1-1/8 inch thick doors and carries a leaf size of 3/4 inch by 3-3/4 inch. The hinge is sold as an individual unit and is commonly installed by carpenters, millwork contractors, and finish trade professionals in commercial and residential applications where a clean, hardware-free appearance is required.

This hinge is suited for interior door installations where aesthetic continuity across the door face is a priority. Typical applications include office doors, hotel room entries, residential interior passage doors, and specialty cabinet or panel doors built to 1-1/8 inch thickness. The satin stainless steel finish provides corrosion resistance appropriate for moderate-humidity interior environments. Installers working on healthcare, hospitality, or high-end residential projects commonly specify this hinge where visible hardware conflicts with design intent.

Installation Notes

Installation requires precise mortising into both the door edge and the door frame using a router or chisels; accurate layout is critical to proper alignment and smooth operation. A licensed carpenter or millwork professional should complete the installation to ensure the mortise depth and position match the hinge geometry. Power to any adjacent electronic hardware such as electric strikes or access control devices should be disabled before beginning work. Follow applicable building codes and door hardware manufacturer guidelines for hinge count and placement based on door weight and height.
