These are great door latches. Nice color, very solid. The only thing that is lacking is that they do not send you a strike plate for the passage doors so the brass plate on the door butts up to the wood surface of the door jamb. Although the strike plate serves a purpose for locking the privacy doors, it would be nice to have them for these as well because they would help keep the door a little more secure if the finger pull on the door side were allowed to be recessed into the strike plate on the jamb side while the door is closed.
