Brass was the most popular finish used during the Victorian era so it makes sense that home restorers are returning to brass today. These Victorian window locks feature the Physical Vapour Deposition (PVD) anti-tarnish brass which creates a very durable and long-lasting finish. From Australian company, Tradco Hardware, they lock with two keys that are supplied with your purchase. When purchasing multiple window locks, these keys can be keyed alike or differently - leave a comment to specify your lock preference when you check out.
