this door is designed to do everything
that you would ever ask of a French door
we actually start with an incredible
locking system it begins with a deadbolt
that when you turn the door that allows
you to open it up the door is a very
thick heavy door but the locking system
is designed so that when you open it
you're opening up multiple points of
lock and contact to begin with the
deadbolt comes out over one inch into
the other door panel when you go to
unlock it and you open up the door
you'll notice that there is a hook at
the top right here and then there's a
hook at the bottom down here and what's
happening is is when you lock the door
what you're doing is those locks are
coming out this one comes in and grabs
to the bottom this one comes in and
grabs to the top and it is capturing the
other door frame when you throw the
deadbolt what you're doing is you're
putting in three points of contact that
you can't raise or lower this door to
try to Jimmy it open and that's actually
grabbing and locking in and holding that
other door or clamping it so that it
will keep you from worrying about
buffeting winds driving rains or kick
ins now when i unlock all of this and
bring this open all of that works great
but depends on the locking system for
the other side of the door so when we
open this side what we're doing is we're
turning the handle and that is driving
up or opening it will pull down a pin
from the top and pull in a pin from the
bottom but when we lock it and we raise
it to lock it it will actually put a pin
that sticks out over one inch at the top
and over one inch at the bottom locking
this panel into the threshold and into
the header of the door system so what
you essentially have is a five-point
locking system for a double French door
