We used to use 2x4's to latch a sliding door for security reasons that had to be bent and removed daily. We installed Security Man in the middle and it's amazing, very easy to install and feels totally safe because children can't open it or the door can't be opened from the inside or outside when the bars are down. If you are looking I recommend this.
