The No 3581 two knuckle lift-off butt hinge has a radiused bushing between the faceted knuckles. A stepped shallow dome terminates each octagonal knuckle. The design is appropriate for traditional as well as contemporary interiors. The hinge is handed; a right-hand hinge is shown. It measures 4-1/2” x 4-1/2” with a leaf gauge of 0.170” and a knuckle diameter of 3/4”. As is true with all hinges, Nanz can manufacture custom versions in any size required. All Nanz plated and patinated finishes are available.
