This is a wonderful antique doorknob set with matching plates, intricately ornamented with a Celtic knot design that covers the entire knob and backplate. This set is in excellent condition. Each plate measures 2 ¼” wide and 7 ¼” tall; the knobs are 2 ¼” in diameter and 2 ¼” deep. This door hardware set is suitable for modern doors that have been predrilled; we carry a modern latch set suitable for use with these knobs. We also have antique mortise locks available.
