What is the difference between the Firestop Plate pictured here and the Wall Firestop item? Do they have different use cases? is one for vertical and one for horizontal?

Yes, this firestop is meant for vertical installations when passing the pipe through a ceiling, whereas the FMI Wall Firestop
is intended for passing the FMI direct vent pipe (5" inner diameter and 8" outer diameter) through an exterior wall.
