Hardware components that enhance the functionality, security, and aesthetics of a door. These include hinges, locks, handles, latches, and door stoppers. Hinges ensure smooth door movement, while locks and latches provide security. Door handles allow easy operation, and stoppers prevent damage from abrupt swings. Fittings come in different materials, such as stainless steel, brass, or aluminum, and are designed to match various architectural styles. Quality door fittings are essential for durability and safety, making them a key consideration in residential, commercial, and industrial buildings.
