Mortice locks differ from other types of locks. They are set inside the body of the door rather than fixed to the surface. The 'mortice' is the space that is cut out to fit the lock into the wooden doors that can be drilled and chiselled out to size. Designed for longevity and strength, they are ideal for frequent use over many years. Internal doors are suitable for fitting 2-or 3 lever mortice locks, whereas only five-lever ones are recommended for external doors. Locks conforming to British Standard 3621 are recommended by insurance companies and identified by the Kitemark on the faceplate. We stock a full selection of mortice locks suitable for all security levels, from bathroom locks to British Standard 5 lever deadlocks in various styles, sizes, and finishes. We are happy to advise you to help you make the proper selection. Lastly, cosmetic options include different finishes such as brass or chrome.
