SOSS 216 Series 4-5/8" Invisible Hinge for 1-3/8" to 1-3/4" Doors
The SOSS 216 Series 4-5/8" Invisible Hinge is engineered for full-size entry doors in wood or metal applications ranging from 1-3/8" to 1-3/4" thick. When closed, the hinge is completely concealed within the door and frame — no exposed barrel, no visible hardware. Built from zinc and steel for heavy-duty commercial-grade performance, this radius corner hinge opens a full 180° as a single-action unit, making it the go-to choice for high-end residential, commercial, and institutional installations where a flush fit and clean aesthetic are non-negotiable.
