Inside: The inside layout will sit inside the metal frame box, meaning the entire metal lip of the vent is exposed. We recommend this for ceiling installations, but it also looks simple and elegant for wall covers.

Wraparound: The wraparound looks just like a piece of art on your wall, covering the metal frame box completely. With a wooden frame, this layout goes around over 1/4 inch of the metal frame. Please ensure you have the necessary space around your vent for this layout. 

Flush: If you don’t have a lot of space around the metal frame (maybe because you have molding around or a trim door is right next to it) and you still like the look of having a wooden frame, the flush will fit just perfect! You will see the sides of the metal box exposed but at eye level, you will see the wooden add-on.
