Q: Can these be painted?
A: Yes - if you wish to paint them yourself you will select the 'White' option.
Q: Are mounting holes necessary?
A: Mounting holes are typically needed for a wall or ceiling application. If you do not want to use screws/mounting holes to attach your covers you will need to have an alternative method of adhesion.

Q: Do i need a damper?
A: This is totally up to you. If you do open and close the flow of air on your covers often, then you should get a damper. If you don't ever adjust the flow of air on your covers then it is likely not necessary.
Q: How do I adjust the damper?
A: The damper is adjustable using a flat head screwdriver.
