Soss 518US26D Invisible Hinge Satin Chrome 4.625 in

Product Description

The SOSS UIP Allegion 518US26D is a wide-throw invisible hinge designed for doors where a clean, hardware-free appearance is required. When the door is closed, the hinge is completely concealed within the door edge and frame, leaving no visible hardware on the face of the door. Measuring 4.625 inches in length with a 1.25-inch width throw, this hinge is suited for residential and light commercial applications. It ships in a satin chrome finish and is installed by carpenters, millwork specialists, and finish carpenters working on interior doors requiring a flush, seamless look.

This hinge is used in interior door installations where aesthetics are a priority, such as conference rooms, hospitality spaces, high-end residential builds, and custom cabinetry or door projects. The wide-throw design allows the door to swing clear of the frame opening, which is important in tight hallways or where full door clearance is needed. It is sold individually and is typically installed in sets of two or more depending on door weight and height.

Compatibility

Designed as an OEM-style replacement or new-installation invisible hinge for interior door applications requiring concealed hardware. No specific compatible model numbers were provided in the product data.

Installation Notes

Invisible hinges require precise mortising into both the door edge and the door frame jamb — a router and hinge mortising template are strongly recommended for accurate placement. Power down any electronic door hardware before beginning installation. Follow local building codes for door hardware clearances and accessibility requirements. Improper mortise depth will prevent the hinge from seating flush and will affect door alignment, so test fit before final fastening.
