What is a mortise lock?

Mortise locks have been around for over a century and are still popular today due to their advanced features and unique versatility. These locks are designed to be installed into a pocket, or mortise, on the edge of a door. They offer superior security, durability, and aesthetic appeal compared to other types of locks.

One of the most significant advantages of a mortise lock is its hand-operated deadbolt. This makes it nearly impossible for someone to pick the lock from outside. Additionally, many modern mortise locks come equipped with advanced features such as keyless entry and remote access control. These added conveniences make them an attractive choice for homeowners who want both security and convenience.

Finally, mortise locks also offer unique versatility in terms of design options. They can be customized with different finishes, knob styles, and keyhole shapes to match any home's decor seamlessly.

Why do you need a mortise lock?

We already said it, but we'd like to reinforce this. When it comes to ensuring the safety of your home or office, installing a mortise lock is one of the most reliable and effective ways to do so. Mortise locks have been in use for centuries and are still popular today due to their improved functionality and superior strength compared to other types of locks.

Mortise locks are designed with a unique mechanism that allows them to be extremely secure against forced entry. They feature a deadbolt that extends deep into the door frame, providing an added layer of protection against intruders attempting to break in. In addition, they often come equipped with a strike plate that is reinforced with steel for even greater strength. And sometimes they are made of a solid one-piece stainless steel, increasing the strength of the lock.

Aside from their security features, mortise locks also offer improved functionality and features compared to other types of locks (coded lock, etc.).

Types of mortise locks

There are two main types of mortise locks:

  1. Sashlocks (Sach locks)
  2. Deadlocks

1. Sash lock

Sashlocks are commonly used in residential homes and commercial buildings. They feature latch bolts that can be locked using a key or turn knob from either side of the door. Sashlocks typically have an additional latch bolt at the top of the lock that can be operated by turning a handle on one side of the door. This allows for greater security as it prevents the door from being forced open even if someone manages to pick or break the lower latch.

2. Deadlocks

Deadlocks, in contrast, do not have an additional latch bolt at the top of the lock. These locks are also installed into the door itself, creating a sturdy mechanism that cannot be easily broken or tampered with. Mortise deadlocks have been proven to be highly effective in preventing break-ins, making them an excellent investment for anyone seeking to improve their security. One of the key features of mortise deadlocks is their durability. They are made using high-quality materials such as steel or brass, which ensures they can withstand significant force without breaking or becoming damaged. Additionally, these locks come in a variety of designs and finishes that make them suitable for any type of door or decor style.
