What material can this be used with?
Pretty much anything! Surface material must be ⅞” or thinner.

Can I install after my floor / surface is already installed?
Yes! This can be installed on existing surfaces. All you need is a scrap piece of material to place inside the inner tray.

Can I use this on floors, wall and ceiling vents?
Sure can! If your walls and ceilings are drywall — the Drywall Pro is also a good option.

Do you make custom sizes or colours?
No, sorry about that!
