It still functions with the angle iron attached because the angle iron does not interact with the door lock or the door swing. If the angle iron is attached to the door it simply swings with the door slab, open or closed. When the slab closes, the angle iron lines up with the door stop (that little vertical, rectangular ridge on the middle of the door jamb). If the angle iron is attached to the door stop itself, like in the second scenario Mike demonstrates here, then it stays in place as the slab swings open and closes. In either case, the purpose of the angle iron is simply to cover the vertical “crack” between the door slab and the door stop, and improve security.
Definitely perfected his craft
how does a door even function if it has an angel iron on the outside and a lock on the inside
