Door Hardware for Interior and Exterior Doors. Every door inside and outside the home serves a specific function. With proper door hardware, doors operate smoothly and provide the security needed in various areas of the home. Sometimes, the simple act of changing out the door knobs can provide a door with a fresh, fashionable update. Most of the french lever handles go well with almost any of the classical style door plates such as Rococo, Renaissance revival, French Byzantine, Windsor, and more. Take a look at our matching antique mortise locks, vintage door plates, or door security bolts to further compliment the style of your doors.
