Standard Front Door Locks (Sash Lock)

Standard Front Door Locks (Sash Lock)

These front door locks have a latch as well as a deadbolt, which means a key is required to lock and unlock the door, and use of handles is required to then open the door. 

This should be the preferred choice for all entry / exit doors on your home as they are British Standard ideal for your front door lock or back doors etc.  They deadlock (and unlock) by turn of a key and only the latch is operated by handle.  This is definitely the most common type of mortice lock and is what we are all most used to.

If you don't want the use of handles then you should consider looking at our deadlocks for front doors.
