Soss 212US10BL Invisible Hinge Medium Duty Oil Rubbed Bronze

Product Description

The SOSS 212US10BL is a medium-duty invisible hinge designed for interior doors with a thickness of 1-1/8 inches. Mortised fully into the door edge and frame, this hinge remains completely hidden when the door is closed, leaving no exposed hardware on the face of the door or jamb. The lacquered oil rubbed bronze finish provides a dark, matte appearance that resists fingerprints and minor corrosion in typical interior environments. At 0.5 pounds per unit, it is lightweight enough for precise installation without adding significant load to the door assembly. Finish carpenters, cabinetmakers, and general contractors are the primary trades that specify and install this product.

The 212US10BL is suited for residential and light commercial interior door applications where concealed hardware is required for aesthetic or design reasons. Common install scenarios include solid-wood interior doors, custom millwork, cabinet doors, and architectural passage doors where surface-mounted hinges would detract from the finished appearance. This hinge is specified when a clean, hardware-free door face is a project requirement.

Installation Notes

Installation is performed by finish carpenters or skilled general contractors and requires precise mortise routing into both the door edge and the door jamb. Power down any automated door operators and ensure the door is removed from the opening before mortising. A router with a straight bit and hinge template is the standard tool for achieving the required mortise depth and profile. Follow all applicable local building codes and manufacturer mortise specifications to ensure proper hinge seating and door swing.
