we have the pins....they go thru the steel centers where the door meet in the middle toward the top.
We also have the steel bar.....they hook on the side and drop down into a latch in the center of the door. when in place looks like a bar going across the center of the door...This one scares me because it just maybe could drop down and latch and lock me out, so we put in velcro on the side so that would never happen. now it has to be pulled away and wont fall down on accident.
Never hurts to double up and the bad guys can see that you have some sort of security devise and maybe will move on. sorry neighbors....
