Sleek and Modern

Very nice vent cover. I needed a register cover/diffuser for the toe kick of my new vanity. The first one I bought was too tall. This diffuser fits nicely. I was able to just cut a hole in the 3/4 inch wood toe kick and slide the diffuser in. It doesn't even need the mounting screws. It looks sleek and minimalist -- a good match for a Shaker style vanity.
