It is an illusion that your current doors are safe when you lock them!
The best door lock , the most secure door lock,......... is a.... LineBacker Articulated Door Restraint
It's not smart to open a door when you don't know who's there!
Do you know how weak your entry doors are? And why?
Just look at how much wood was drilled out to install the hardware. That's only 3/8 of an inch of wood left to protect against breaking.
This is where the strike plate is installed with very short screws. So you can see why it doesn't take much of a kick to break through your doorway
Short screws into very little wood , no wonder it's easy to kick-in! See the side view of the door jamb (in white) in the picture to the right.
Hidden behind the drywall is the door frame. (The double or triple 2 x 4s ). It is this strength component that the LineBacker mounting brackets are attached to. The white board on the left in the circle is the door jamb. It is in this 3/4" board that your strike plate is mounted
Four 3 1/2" screws go through the mounting brackets into both sides of the door frame,(the two by fours inside the drywall) just outside the trim, to anchor the LineBacker. It cannot be any stronger!.
Being squeezed against the door, It becomes unified to the door 'frame' and is now immovable. Since it cannot move, you are protecting not just the door but also the door jamb from damage.
Just rotate the handle, slide it aside, and a heavy duty pin hinge will allow the bar to articulate and still be anchored to the frame. No one can force the door open!
Heavy duty steel Pin Hinge is exposed when the handle slides aside
The quick release safety catch is not reachable from the open side of the door.
Just swipe your hand across the release tab and the bar falls away in an emergency .
