I've seen then on lots of doors but I can't determine what its called.
The installer routes out an edge of the door all around and installs a
metal lip that marries to an opposing lip installed the same way on
the door frame.

Is there a specific name for this type because I sure cannot seem to
find one searching online.

Suggestions please? Thanks.
