Handua 30"W x 8"H [Duct Opening Size] Steel Return Air Grille | Vent Cover Grill for Sidewall and Ceiling, White | Outer Dimensions: 31.75"W X 9.75"H for 30x8 Duct Opening

I ordered this grille to replace a smaller air return grille that was making wind noise with my system. I was hoping that the larger surface area of this grille would eliminate the obvious restriction of the smaller grille and it did not disappoint. My system is now perfectly quiet - no wind noise from in rushing air.Something for every DIY person to think about when sizing your grille is if that grille will restrict the air being pulled into the AC/Heat unit. That restriction will cause a whistling or rattling noise. It will also starve the AC unit of the maximum air it is trying to pull in, creating that noise mentioned, and causing the system to work harder than it needs to - possibly leading to early failure of the fan.One thing to note is that home builders will tend to install the cheapest and smallest air return grilles they can get away with as long as it meets minimum requirements - which was clearly the case with my house. Originally, I ordered a different Handua grille which fit the hole on my wall cavity exactly. It was a really great kit, but it turned out to be too small for my system. So I ordered this one which is about 1/4 larger and viola, problem solved! Perfect silence, no negative pressure sucking the grille onto the wall.In the end, have to say that all of these Handua grilles seem well made, and they look really attractive on the wall. It's nice to have a new, handsome grille to replace my tired, yellowed 24 year old grille with this fresh new one. And now that it's nice and quiet, with no inlet restrictions, I am a happy DIY guy. And if my AC unit had lips, I'm sure it would thank me too now that it can breathe better.

Great grill but the screws are junk…

Product was shipped fast and I perfect condition. Works great

Worked great.

After 50 years our intake grill for the heater was showing some rust. Rather taking all the time to remove the rust and repaint we replaced the heater intake vent grill. The cost was reasonable and I didn't have to work hours restoring our old vent grill. Well worth it.
