These hinges are milled from 6mm thick solid brass stock to precise dimensions and are designed to last a lifetime. They feature stainless steel hinge pins and our standard Brusso burnished finish. The leaf measures 13mm wide x 51mm long. The inset is 45mm long. The hinge is sold in pairs unhanded with brass screws included.
