Mortice locks come in a few different varieties, the most common being dead locks and sash locks. What’s the Difference Between a Mortice Deadlock and a Mortice Sash lock? You might do this if, for example, you’re running a bed-and-breakfast, or you’d like to keep garage doors under lock and key for security reasons.įor most homes, however, you may need to install entirely new doors that can accommodate the sheer size of a mortice lock. They can, however, also be used on internal doors to control who has access to certain parts of the house. Mortice locks are primarily found on external doors. What Type of Doors are Mortice Locks For? Finally, the escutcheon plates sit around the handle to preserve the look of the door. There’s also the faceplate, which is often a separate piece of metal that attaches to the door, facing the strike plate. This ensures that the bolt slots straight in, rather than scuffing against the surrounding wood. These include the strike plate, and a piece of metal surrounding the mortice. If the wrong key is used, the key either won’t fit into the lock, or it won’t catch all of the levers in the right way.Ī mortice lock will also incorporate several other components. If the right key is used, then all of the levers align, and the whole mechanism can be rotated to withdraw and extend the bolt. The cut of the key is designed to match the levers on the interior of the matching lock. Inside this mechanism is a space for the bolt to retreat into, as well as a series of parallel levers which are attached to the rear of the bolt via a small piece of metal called a bolt-stop. For this reason, it is unlikely to find them installed on internal doors, and most prominently on entrance doors to your home. This means that the door in question must be of a certain thickness, in order to accommodate the lock. How do Mortice Locks Work?Ī mortice lock relies on a relatively large mechanism, which slots into the interior of the door. It’s important to understand how a mortice lock mechanism works before deciding whether you should have one for your external doors. When the bolt is in the mortice, the door is unable to move and is securely locked. These earned their name thanks to the pocket (or mortice) that the bolt slots into, which is cut into the internal face of the doorframe. One of the most readily available and secure types of lock is the mortice lock. Locks come in several varieties, each with its own strengths and weaknesses. While it might only be a few inches from end to end, the lock on your front door is arguably the most important security feature in your entire home.
