To use this Hadrian door hardware kit, first, make sure your door is a left-handed out-swing type. Then, carefully attach the aluminum wrap-around hinge to the door and the door frame using the provided screws. Ensure all connections are tight for proper function. When using the door, don't apply excessive force to the hinge to avoid damage. For maintenance, regularly check the screws to make sure they're not loose. If the hinge gets dirty, you can clean it with a mild soap and water solution, then dry it thoroughly. This will help keep your door hardware kit in good working condition for a long time.
