Break In
Don’t let this happen to you! Mortice locks offer better security.

Why mortice locks offer better door security

If you are considering what is the most secure lock to install on your front entry then definitely consider using a mortice lock? Mortice locks offer a higher level of security than a tubular latch.

The choice

If you’re looking to replace the locks and entry sets on the doors around your house, you’re really looking at a choice between mortice and tubular style lock systems. While tubular systems are popular and found in both residential and business applications, you should know why mortice locks offer higher security for doors in both businesses and homes before making your choice.

Going tubular?

Tubular locks gained general popularity because they are quicker to fit and they do not require special tools or training to install, and are therefore seen as a relatively secure, simple entry system. However, it’s exactly for these reasons that mortice locks offer a greater level of security.

How do break-ins happen?

The fact is that most home burglaries happen when the strike plate of the door is kicked in or struck with a heavy object. By weakening the lock, or simply smashing through the door around the entry system, burglars are able to access your home. A tubular latch pictured on the right has far less structural strength than a mortice lock shown below.

What is a mortice style lock?

Mortice is a carpentry term meaning a slot or recess cut out of a piece of wood, so that another piece with a matching projection can be fitted
into it, making a tight joint (mortice and tenon joint.) A mortice type lock similarly fits into a recess cut into the edge of a door, as opposed to a Rim Lock that is fitted onto the surface of a door.

For a mortice style entry system, the door itself is cut to include a pocket where the lock is installed. By placing the lock into this pocket inside the door, you’re creating a secure system that uses the strength of the door (plus the reinforcement of the lock’s construction) to protect it from break-ins. A mortice lock has up to five times more strength!

Builders and installers don’t like fitting mortice locks so they persuade home owners to use tubular latches instead! Whilst the initial investment may be a little more – what is your safety worth?

The benefits of a Mortice Lock

Consider the benefits of a mortice lock over against a tubular latch;

  • Usually a lifetime warranty
  • Up to 5 times stronger than a tubular latch
  • Anti drill and tamper proof – hardened cylinder
  • Larger dead bolt throw – 40% stronger
  • Heavy duty spring and mechanism – stronger spring which stops the handle sagging
  • Peace of mind
  • Comes with integrated deadbolt
  • Much stronger outer housing
  • Screws thread right through using tie bolts that sandwich the mortice lock between the timber of the door from both sides.
  • Mortice locks can be fitted with a euro cylinder enabling a minimum of 2,000 key differs, which means a thief would have to carry 2,000 keys for your make of lock to be certain of unlocking your door and even then he could be there for 3 hours trying all the keys before he gets lucky!

Do I need a professional installer?

If you’re handy around the house or have access to the equipment you need, you’re probably safe to install your own mortice locks. However, there’s no harm in calling in an expert if you’re looking for absolute piece of mind.

You may consider using a professional installer, because:

  • Not all mortice locks are the same, so you require specific measurements for optimum security.
  • Some mortice locks suit interior doors better than others.
  • Different kinds of mortice locks include single or double cylinder, or dummy sets.
  • A professional installer will use specialized tools like a mortice saw to cut into the door.
  • Most installations come with some manner of guarantee.

Securing peace of mind

There really isn’t a price you can put on peace of mind. If you’re looking to access the maximum amount of security you can, you can see why mortice locks offer higher security for doors in your home or your business. While tubular locks are popular, mortice  locks offer more bang for the buck and help protect your valuables more securely.
