The Schlage Georgian Antique Brass Keyed Entry Door Knob is perfect of use on exterior doors. The Georgian knob features a design inspired by Georgian-style homes in New England, and looks especially warm and inviting when wrapped in our Antique Brass finish. The knob unlocks when the door is opened from the inside, allowing you to leave quickly and conveniently and re-enter easily. Plus, it was designed and tested with strength and durability in mind.
