Mortise Lock Fitting (Deadbolt - Deadlock)
The fitting of a mortise lock is something most average
DIY persons can undertake. With a few hand tools and a modicum
of patience you should be able to install a door lock that
offers superior levels of protection and save yourself some
money into the bargain
A mortise lock can provide improved front, side and back
door security by being physically embedded or mortised into
the door itself, as a result your door is less vulnerable
to a ram or forced attack
Where should you fit a mortise lock? It's recommended that
all entrance and exit doors are fitted with a heavy-duty
deadbolt locking mechanism. This is in addition to the usual
surface mounted or cylinder-locks that most doors already
have fitted as a matter of course
4 Levels of Deadbolt Security
Mortise locks are available with 2, 3, 5 or 7 lever mechanisms.
The higher the number of "levers" the more difficult
it is to pick the lock. For front, side and back doors it
is recommended that British Standard 5 or 7 lever devices
are fitted, these are available from most locksmiths including
ourselves
Mortise lock case sizes
Mortise locks come in a range of different case sizes. The
case size is the measurement between the faceplate and the
back of the lock as measured in millimetres (typically 54
mm, 67 mm or 80 mm). The case size measurement therefore denotes
the depth of the mortise slot in the door

skills to install an embedded deadbolt into a door
As with all DIY tasks safety is very important, please
take all precautions to ensure your safety. You also need
to be aware that your door could be damaged, at least cosmetically
if you mess up. If you are unsure of your ability then we
highly recommend you call your local locksmiths
