This practical cabinet hinge is a standard 3/8 in. overlay inset hinge, specifically designed for 3/8 in. inset cabinets. It is a perfect replacement for original 3/8 in. doors. The overall length of the hinge wing is 2-3/4 in. (70 mm), and the hole center distance is 2-1/8 in. (54 mm). Each set contains 50 pieces (25 pairs) of matte black cabinet hinges. Each 3/8 in. inset hinge comes with 5 mounting screws. With surface mounting, there's no need to cut mortises, making the installation easy and quick. It features quiet and soft self-closing. Equipped with bumpers, when the opening and closing angle of the cabinet door is less than 30°, it will close automatically and quietly. This effectively reduces noise, protects the furniture, and keeps your home environment peaceful and safe. Made of 1.5 mm thick durable stainless steel, it is sturdy and long lasting, and is an ideal choice for kitchen, bathroom, and other face frame cabinets or doors.
