These are a great way to add some classic or contemporary styling without breaking the bank. They are suitable for floor use right out of the box, but if used in wall applications you'll need the optional wall mount clips unless you have 6 inch widths, in which case you can use the included matching screws. For ceiling applications it is possible but you'll need to talk to us and see if you are up for the necessary customizing which is a hassle but not too difficult.
The faceplates are 2 millimeter thick steel, which is way thicker than most budget registers. They automatically come with dampers. These are typically on hand and ready to ship out.
