 We trust our homes to Schlag. With Schlag custom, homeowners and designers have a lot of flexibility. You can mix and match the door hardware. Take your front door, for example. You can have one finish on the exterior of your front door that matches the outside of your house. But on the inside of that same door, you can have a totally different finish that matches your closet and hallway doors. At any time, you can change your door hardware from a lever to a knob or function passage to a privacy locking door simply by adding the innovative locking pin.
