The Brinks Commercial Ball Bearing Door Hinge provides smooth and quiet door operation for interior or exterior doors that are light-medium weight. Internal ball bearings reduce friction and noise which allows the door to open and close effortlessly and quietly. No more creaking doors. Hinges come predrilled for quick and easy installation and are reversible so you can use them on left or right handed doors. They are constructed of corrosion resistant steel for durability and also have a non-removable pin for added security and protection when facing externally.
