Using these Deltana hinges is easy. Just attach them to your door with the included #10 x 1 - inch wood screws. Make sure to align them properly for smooth operation. When installing, handle the hinges gently as they are made of solid brass. For daily use, avoid slamming the door to prevent damage. To maintain their appearance, wipe them with a soft, dry cloth regularly. If they get dirty, you can use a mild soap and water solution, then dry them thoroughly. This will keep your hinges looking great and working well for years.
