165 Degree Soft Close Kitchen Cabinet Hinge + Frameless Plate Hinge is made from nickel-plated steel. The hinge fits into a 35mm (1-3/8″) cup drilled in the back of the door. Cup depth is 13 mm (1/2″). The center-to-center screw hole dimensions on the hinge cup are 35 mm (1-3/4″). Door Reveal – the reveal is the gap that is found (when the door is closed) between the edge of the door and the cabinet side panel that the door is hinged to. The reveal dimension is determined by the “bore distance”. The bore distance is the distance from the edge of the cup drilled in the back of the door to the edge of the door. You can use any bore distance from 3 mm to 8 mm (1/8″ to 5/16″). The center-to-center screw hole dimensions on the hinge cup are 35 mm (1-3/4″). If your current hinge is 1-3/4″ or the less common 1-7/8″ you can install this hinge without re-drilling the screw holes. For 1-7/8″ screw hole dimensions, the screw will go in at a slight angle but usually works without a problem. Make sure to order at least two hinges for each door that you are hanging.
