I just replaced the door on my workshop
and while I was working on it I posted a
picture of it on Instagram and I got a
comment asking me about security on a
door that swings out like this in
particular being able to open the door
from the outside with just a knife
exterior door locks like this are made
to stop that from happening
they have this pin that's right beside
the latch that when it's pressed in will
stop the latch from retracting I can
probably demonstrate this a little bit
better with these two that I have here
when the door is closed that pin will be
up against a strike plate as long as
everything is lined up correctly that is
if that pin goes inside the strike plate
hole it will defeat the operation the
other one that I have here is an example
of a passage lock like you'd find on a
bedroom or a closet inside your house
and these don't have or need one of
those security pins the lock that I have
on my shop is a cylindrical lock set but
mortise lock sets have the same thing
except the pin is usually right below
the latch when that pin is lined up and
working properly you won't be able to
pry open the latch with just a knife but
of course that doesn't stop somebody
that wants to break in from trying but
there is a piece of hardware that you
can install that will guard against that
latch guards like this bolt through the
door and some of them have pins that
will go into the frame itself and make
it very difficult to pry that apart
another thing about out swinging doors
like this is the widespread belief that
you can pull the pins out of the hinges
and then open the door that way and
while you can't get hinges that are very
difficult to take the pin out of from
the outside if your door fits correctly
in the opening even with the pins taken
out fully it will be very difficult to
remove the door without bending the
hinges as well the barrel of the hinge
will get in the way
