Mortice Lock

The Basic Mortice locks are a common type of lock used on wooden doors. They come in two parts: the lock mechanism that contains a deadbolt, and a latch. The latch is installed on the door, while the lock mechanism is placed in a groove, known as the “mortice.” The other part of the lock is the striker plate, or keep, which goes inside the door frame and holds the latch or deadbolt in place. To operate the lock, you turn the key to retract the deadbolt. If the lock has a latch, you can release it by turning the doorknob or pulling the door handle. At MB DIY, we offer a reliable mortice lock, including Mortice Sash Lock, Mortice Deadlock, Tubular Latch, 3 & 5 Lever Mortice Lock.


Mortice Lock Selection Made Easy

When choosing a mortice lock, it’s important to keep in mind the level of security you need. Generally, the more levers a lock has, the more secure it is. A 3 Lever Mortice Lock is often used on internal doors and is a cost-effective option, while a 5 Lever Mortice Lock provides added security and is often used on exterior doors.

The Easy Way to Install a Mortice Lock

If you’re installing a mortice lock, you’ll need to decide whether to replace an existing lock or install a new one into a new door. Replacing an existing lock is straightforward – simply measure the old lock, unscrew it, and replace it with the new one in the same location. Installing a new lock into a new door is a bit more involved and may require the assistance of a skilled DIYer or joiner. This process involves measuring the lock, cutting a mortice into the door to accommodate it, and routing a hole for the lock.

The Ideal Mortice Lock: Available at MB DIY

At MB DIY, we understand that everyone’s security needs are different, which is why we offer a variety of Mortice Locks to meet your needs. Whether you’re looking for a simple and affordable lock for your interior doors, or a high-security lock for your exterior doors, we have a lock to fit your needs.

Here are the different types of Mortice Locks that we offer at MB DIY:

  • Mortice Sash Lock

A Mortice Sash Lock is a type of lock commonly found on entry and exit doors that are opened and closed frequently. This lock has two parts – the deadbolt, which provides added security, and the latch, which keeps the door closed when it’s not locked. To open the door, you can use a key to unlock the deadbolt or simply turn the door handle to release the latch.

Mortice Sash Locks are a convenient solution for doors that are frequently used because they allow you to easily lock and unlock the door without having to use a key every time. This makes them a popular choice for homes, offices, and other buildings that have entry and exit doors.

  • Mortice Deadlock

A Mortice Deadlock is a type of lock that only has a deadbolt and does not have a latch like a Mortice Sash Lock. This lock is operated solely by a key, which makes it a great option for rooms that need to be locked at all times, such as plant or equipment rooms.

One of the benefits of a Mortice Deadlock is that it can be manually operated from both sides of the door, which makes it a convenient option for rooms that need to be locked and unlocked frequently. This type of lock is also a good choice for rooms that contain sensitive or valuable items, as it provides a high level of security.

When installing a Mortice Deadlock, it’s important to make sure that the lock mechanism is installed in the correct location and that the deadbolt extends far enough into the door frame to provide adequate security. If you’re unsure about the installation process, it’s best to consult a professional locksmith or handyman.

  • Tubular Latch

A Tubular Latch is a type of lock that is designed to keep a door closed when it’s pressed shut. Unlike a Mortice Sash Lock or a Mortice Deadlock, a Tubular Latch does not have a deadbolt or a key-operated mechanism. Instead, it relies on a simple latch that is released by pressing down on the door handle.

Tubular Latches are often used on internal doors, such as bedrooms, bathrooms, and closets, where there is no need for a high level of security. This type of lock is a convenient and low-maintenance option for these types of doors, as the Tubular Latch does not require a key to operate and does not have any moving parts that can wear out over time.

  • 3 Lever Mortice Lock

The 3 Lever Mortice Lock is a type of lock that is best suited for interior doors that need to be kept separate for security reasons. This type of lock provides a basic level of security and is often used for rooms that contain sensitive or valuable items, such as an archive room in an office or a private office where confidential material is stored.

One of the benefits of a 3 Lever Mortice Lock is that it is relatively inexpensive to install compared to other types of locks, such as a 5 Lever Mortice Lock. Additionally, it is durable and can last for many years without needing any maintenance or repair work.

  • 5 Lever Mortice Lock

The 5 Lever Mortice Lock is a type of lock that provides added security for your home or office by making it more difficult for intruders to break in. This type of lock is often used on exterior doors, such as front doors, back doors, and patio doors, to provide a high level of security for your home or business.

One of the benefits of a 5 Lever Mortice Lock is that it provides a higher level of security compared to the 3 Lever Mortice Lock. This makes it a great option for homeowners and business owners who want to keep their property safer and more secure. In fact, some insurance companies may require that a door be installed with a 5 Lever Mortice Lock in order to reduce the insurance premium.

Overall, the 5 Lever Mortice Lock is a reliable and secure option for exterior doors. With its added security features and insurance company requirements, it’s a popular choice for homeowners and business owners who want to keep their property safe and secure.
