I got 9 flush mount wood vents in Brazilian Cherry, they went in fantastically with the new floor. One minor note, I had 3 with the dampers installed, and I had measured my vents correctly but the fit is extremely snug / you have to be perfect in locating it. I ended up cutting through the subfloor to expand the vent size slightly to install the ones with dampers. Maybe it's just a me a problem, but it seems like if the damper was, for example, 3.5x9.5 for a 4x10 vent, the install would have been much easier, especially if retro-actively adding these to an existing floor. I will be doing that later this year and I expect to be placing another order here when that time comes!
