Choosing A Door Lock For Wooden Doors

 

Choosing the right door lock for your timber doors is incredibly important if you want to keep your house secure. There are many different types of door lock to choose from and the best choice will be dependent on the type of door you need to secure. Here is a quick guide to door locks to help you make the right decision for a safe and secure home.

A & T Carpentry give you an overview of the 6 most used lock types in the home.

Mortice Deadlock

This type of lock is a bolt operated with a key.  Its usually used alongside another type of lock such as a nightlatch. Fitted around waist height, the door can be locked from the inside or the outside with a deadlock.

Mortice Sashlock

This kind of lock is a combination of a mortice lock and a latch mechanism. It enables you to open and close the door without having to use a key, but you can also lock it securely with a key when you leave your home. For the best security choose a 5 lever sashlock.  If you need to secure internal doors with a key then choose the standard 3 lever sashlock.

Nightlatch

Ideal for securing external entrance doors, the nightlatch allows you to open and close the door from the inside, with a lever,  as you would with an ordinary doorknob or handle. It will lock simply by you closing the door again. From the outside,  a Yale  key is required to unlock the door.
