Soss 103CUS4 Invisible Hinge Satin Brass Light Duty

Product Description

The SOSS UIP ALLEGION 103CUS4 is a light-duty invisible hinge finished in satin brass, designed to mount completely within the door and frame so no hinge hardware is visible when the door is closed. The hinge measures 0.5 inches wide by 1.5 inches in length and is engineered for use on doors up to 0.75 inches thick. At approximately 0.2 pounds per pair, it is a compact, low-profile solution suited for cabinet doors, lightweight interior doors, and specialty millwork applications where a clean, hardware-free appearance is required. Licensed contractors and finish carpenters are the primary installers of this product type.

This hinge is appropriate for residential and light commercial applications where aesthetics and clean lines take priority over exposed traditional hinges. It is well suited for interior doors, cabinet panels, display cases, and decorative millwork assemblies that require a flush, unobtrusive pivot point. The satin brass finish coordinates with matching hardware in contemporary and transitional design schemes. Each unit is sold as a pair, with a case quantity of 10 pairs available for larger projects.

Compatibility

Designed as an OEM-style invisible hinge replacement for light-duty door applications requiring a 0.75 inches door thickness and a 0.5 inches x 1.5 inches mortise cutout.

Installation Notes

Installation is typically performed by a licensed finish carpenter or general contractor. Precise mortise routing is required on both the door edge and the frame jamb to seat the hinge flush; use of a router with a correctly sized template is strongly recommended. Ensure the door is properly supported and all finish work is complete before final installation. Follow applicable local building codes for door hardware installation in the jurisdiction where the work is performed.
