These high quality 3-knuckle Quadrant Hinges are extruded from heavy .078 brass, carefully polished and lacquer coated to prevent tarnish. We've always liked their looks, with only one reservation: they are constructed without left and right versions and so lack "mirror images" when viewed on opposite sides of a box - an aspect which some may find unsettling. We think that its beauty and agreeable price will overcome all objections.
