The screws holding this security bar in place are 1/4 inch long! They didn't even stay long enough to finish installing the bar. I use a board on the bottom of a sliding door. My grandson will figure it out and figure it out in half a second, but so far so good. The bar comes in 3 pieces and you have to check it almost daily to make sure it hasn't slipped down to a smaller size.
