DHD International Inc. released a 1 15/16-inch by 6 1/2-inch bottom hydraulic self-closing hinge. The hinge, manufactured in Italy, is the same size as standard patch fittings and meets the same U.S. pivot distance standard of 2 5/8 inches. It can be retrofit onto doors that already have a standard free-swinging bottom patch fitting in situations where an owner wants to change to a self-closing door. The self-closing hinge is available in all major finishes.
