Mortice Sash Locks require both a key and a handle to operate the lock. The handle operates the latch element of the sash lock, whilst the key operates the dead lock. These types of lock are often installed on front doors, although they can also be used on other doors as well.
For many main entry doors, such as front or back doors for your home, your insurance company may specify the need to have a British Standard approved lock. We have a range of these types of lock here, and will be happy to advise you on the most appropriate lock to select for your requirements too.
