The picture doesn't begin to do justice to beauty and high quality of the fluted glass knobs in this interior passage door knob set. This set includes all of the hardware needed for one interior door including a pair of doorknobs with spindle, 2 traditional-style stamped solid brass roses in polished nickel with 3 screw holes, tubular spring latch, face plate and full lip strike plate. These sets are ready to be installed on either old or new doors with the standard pre-drilled 2-1/8" holes. This set does not include a locking mechanism. The rose is 2/14" in diameter. This item is made from high quality nickel plated brass.
