Soss 216US10BL Invisible Hinge Oil Rubbed Bronze 1-3/8 in Doors

Product Description

The SOSS 216US10BL is a medium-duty invisible hinge designed for interior doors with a thickness of 1.375 inches. When installed, the hinge sits completely concealed within the door and frame, leaving no exposed hardware on either face. This makes it a common choice for high-end residential and light commercial finish carpentry where clean sightlines are specified. The lacquered oil rubbed bronze finish provides corrosion resistance and a consistent appearance. Installation requires precise mortising into both the door edge and the frame jamb. Finish carpenters, millwork installers, and skilled trim carpenters are the primary trades working with this product.

The 216US10BL fits standard 1.375-inch interior doors and is suited for residential interior applications including bedroom, closet, and passage doors where concealed hardware is specified by an architect, designer, or finish schedule. It is sold individually as a single unit. The invisible hinge format is appropriate for medium-duty swing cycles typical of residential door traffic. Projects specifying no visible hinge barrels on flush or stile-and-rail doors are the primary application scenario.

Key Features

• Fully concealed when door is closed — no exposed barrel or leaves visible on door face or frame face
• Medium-duty rating suited for standard residential interior door weight and swing frequency
• Lacquered oil rubbed bronze finish for durability and consistent color retention
• Designed for 1.375-inch door thickness
• Sold as a single unit — order quantity matches installation requirements

Compatibility

Designed as an OEM-style replacement or new-installation invisible hinge for standard 1.375-inch interior doors requiring concealed hardware.

Installation Notes

Installation requires precise mortise routing into both the door edge and the door frame jamb — a router with a template guide is the standard method. Power down or disable any electric strike or access control hardware before working in the frame. Follow the door and frame manufacturer's installation template to ensure proper hinge alignment and full door swing clearance. This work is typically performed by a finish carpenter or millwork installer; improper mortise depth will prevent the door from hanging flush.
