Waterfall edges and graceful curves at the top and bottom of the plate provide a classic, but dignified update to your exterior door hardware. Ideal for doors that are 84 inches or higher, where a standard height plate would not look to scale. The door is opened by a thumb latch on the exterior and by a knob on the interior. On the deadbolt, there is a keyed lock cylinder for use on the outside of the door while a thumb turn is used to lock the door on the interior.
