Double Hook Mortise Lock
The double hook mortise lock is one of the most important components of any aluminum, wood, or vinyl sliding door. It provides security and protection, while also ensuring smooth and effortless operation of the door. In this article, we will take a comprehensive look at the double hook mortise lock, how it works, its components, and how to identify the right hardware parts for the lock.
What is a Double Hook Mortise Lock?
A double hook mortise lock is a special type of lock that is designed for sliding doors. It consists of two hooks (sometimes called bolts), which engage the top and bottom tracks of the door frame, as well as a mortise lock mechanism that is installed within the door. Together, these components provide a secure, unbreakable lock that cannot be pried open or forced. Double hook mortise locks are commonly used in high-security environments like homes, offices, and commercial buildings, but they are also becoming more popular with homeowners who want to upgrade their sliding doors.
How Does a Double Hook Mortise Lock Work?
The double hook mortise lock is installed within the door and is operated using a thumb-turn or key. When the lock is engaged, the hooks extend from the lock body and engage with the top and bottom tracks of the door frame, preventing the door from being opened. The mortise lock mechanism itself is fixed to the door and is usually composed of a deadbolt, latch, and handle.
The hooks themselves are usually made from hardened steel or other durable materials, ensuring that they cannot be easily cut or damaged. This, in combination with the mortise lock mechanism, makes the double hook mortise lock one of the most secure types of locks available for sliding doors.
Components of a Double Hook Mortise Lock
The double hook mortise lock consists of several key components, each of which plays an important role in ensuring the lock’s durability and functionality. These components include:
- Lock Body
The lock body is the main housing of the mortise lock mechanism. It is typically made from metal and contains the locking mechanism, which consists of a deadbolt and a latch that extend into the door frame. The lock body is installed into the door, typically by being screwed into a pre-cut mortise or recess.
- Hooks
The hooks are the key security components of the double hook mortise lock. They extend from the lock body and engage with the top and bottom tracks of the door frame. The hooks are usually made from hardened steel or other durable materials, and are designed to withstand cutting or prying.
- Thumb-Turn or Key Cylinder
The thumb-turn or key cylinder is the component of the lock that is used to operate it. The thumb-turn is a knob or lever that is turned to engage or disengage the lock, while the key cylinder is a lock that is operated using a key.
- Strike Plate
The strike plate is the metal plate installed on the door frame that the hooks engage with when the lock is engaged. It is typically made from steel and works in combination with the hooks to ensure that the door cannot be forced open.
