Alpha Corporation's auxiliary lock V-570 for hinged doors, used but in working condition. The door thickness it can be installed on is 33-40mm. This is a used item removed during a lock replacement. It is in working condition, and while one of the two screws and strike plates has rust, the rest is relatively clean. The keys include the original key, which has hardly been used, and a frequently used spare key, totaling two keys, one less than new. There are no other missing parts. Of course, it will be sent anonymously.
