I can’t believe someone isn’t posting that has some experience with doors with sidelights. I have lived with a door with two sidelights, for 32 years and haven’t an ounce of problem with sagging, or someone breaking in. I have actually had two doors with double sidelights over the last 32 years. The first 20 years I had a steel door that started to rust on the bottom and for the last 12 years, I’ve had a fiberglass door and nether has sagged. As for security, the latch I have, is a three point latch that takes two hands to unlock and open. I’m not saying some couldn’t break in, from the outside, by breaking the sidelight, but it’s not easy figuring out the combination, to open the door from the inside.
