The Schlage Plymouth handle set with Plymouth Knob in Bright Brass is perfect for use on exterior front doors. The charming Plymouth knob is clean and adaptable while the Plymouth handleset features an oval shape and straight forward design. F-Series handlesets are furnished with 7/8 wrought brass cylinder trim rings. The cylinder trim rings are reinforced by a tapered die-cast security insert installed under the trim ring for resistance to wrenching or prying the cylinder unit.
