The mortice locks have traditionally featured on old, heavy doors, but are no making there way into the modern home, and are incredibly versatile and functional and available in satin chrome. Mortice locks are extra secure because they use a pocket on the door frame for structural support. The locks themselves are often heavy duty, and will help you to keep your home secure for years to come and are usually combined with pull handles.
