What material can this be used with?
Pretty much anything! Surface material must be between ⅛” to ¾”.

Can I install after my floor / surface is already installed?
No, this model must be mounted before the surface material, on the subfloor. If your surface is already installed, check out the OG or Aria Lite.

What is the difference between Flushmount Pro and Flushmount Lite?
The Flushmount Pro is made entirely in steel. The Flushmount Lite is made in a combination of ABS plastic and solid steel. Both models have air flow control capabilities. The Flushmount Lite is stronger, and best for high-traffic areas. The Flushmount Pro is not graded for high-traffic areas. 

Can I use this on floors, wall and ceiling vents?
Sure can! This is best used on walls and ceilings that have wall coverings (like tile, wood etc.) If your walls and ceilings are drywall - the Drywall Pro is a better choice.

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