HVAC Premium 14''w X 8''h Aluminum Adjustable Return/Supply HVAC Air Grille - Full Control Horizontal Airflow Direction - Vent Duct Cover - Single Deflection [Outer Dimensions: 15.85''w X 9.85''h]

These are perfect for wall transfer grilles where no additional duct-work is possible or feasible - I bought the 24w x 10h grilles for over-the-door air returns, and the 12w x 18h grilles for lower wall transfer air returns (to create a high-low air return in 3 separate rooms). I had first thought of painting the frame edges to match our door trims but may decide on that later, as they are quite nice as they are (bright white, as in most typical white door frame paint colors). You wouldn't want to paint the louvers without a great deal of care, they are lightweight and only rest, albeit fairly tightly, in grooves within the frame, painting them may cause the louvers to stick or wear out in time - do so with caution if you're set on painting them. The louvers are easy to adjust if you are gentle and use the center of them to adjust - doing otherwise (i.e., from the far edges/ends of the frame), may warp them over time. The actual frames are sturdy but take care not to drive the screws in too roughly or deep, as it could cause a noticeable 'divot' on the frame (there are 3 screw holes for the 24w x 10h, 3 on top and 3 on bottom, screws are included in order). The 12w x 18h only has 2 screw holes (on left and right sides). A plus is that these look so much nicer than the stamped curved louver non-adjustable grilles you find at big box home improvement stores, and the air flow ('free space') is far better - being able to adjust them however you need, will provide you plenty of return air space, as long as you first account for the size of your A/C or furnace unit (tonnage), the size of your room, how much air your supply registers are putting out, whether your room doors are generally kept open or closed, and determining how much room air flow you need in the room for more comfortable moving air when using your furnace in winter, or A/C in summer.Helpful tips: #1- A simple test you can perform to guesstimate how much additional airflow you need so you can measure your grilles: With the system on and the door closed ( standing outside of the door, ) place your hand at the bottom of the door. If you have a strong flow of air coming from that gap under the door (the 'undercut'), you more than likely need a return in that room. There is a good chance that you are supplying a large amount of air to the room and it is having problems getting back to the system ('positive pressure' while the rest of the home is 'negative' pressure, this puts a lot of stress on your HVAC system and it's life will be shortened somewhat considerably). You can either undercut the door more than it is (unsightly for most people and does little to actually create more air flow), or, install air transfer grilles (or spend a lot of money to have HVAC professionals install ducted returns in which you'll have to give up valuable interior real estate to fit additional ductwork). Another way to test: Start with all interior doors open. Turn the fan to "on" at the thermostat. feel the supply air flow from the register in the room, then have someone close the door to that room, if the air flow is reduced much, then you need a return or return path from that room. You can also open the door just enough to feel a small amount of air pull, use a tape measure to measure height and width of the door's cracked open space, multiply it by the door's undercut space, and the total is the amount of air flow (sq in) you will want to start with before measuring your grilles. Ideally, you want your grilles larger than the supply register in that room, because you want the supply air to travel across the room, through the return air grille, and back to the nearest vented or ducted return in the home that connects to the air handler for exchange.Tip #2: Depending on your room and how much wall space and/or over-the-door space you have available, you may have to settle for a smaller grille (but try to keep it larger than your supply register in the room) - because chances are, you'll find studs where you want to install your grille(s). Measure both the cut opening you want, as well as the grille's frame edge in width and height (both are noted on the product page for each grille available for purchase), use a stud finder to determine how much, if any, alteration of the space/studs you will have to alter, otherwise, measure the cut opening and hopefully you could avoid hitting studs, and rather, install cut opening of the grilles "between" the studs.Tip #3: For newbies, before cutting into sheetrock or other wall materials, turn off your electrical circuit breakers first, because you don't know where potential wiring will be until you've cut a hole large enough for you to see inside the wall cavity where wires or tubing have been installed. If you don't know what you're doing, hire a pro!Tip #4: After you've cut the opening(s) for your grilles, you will want to seal the open cavity top/bottom/sides - you can use sheetrock and seal all connecting pieces with caulking, or use cut 2x4's and caulking to shore up the cavity. Sealing the space's sides/top/bottom prevents air from escaping into the wall cavity or through unseen cracks in the walls/ceiling where that conditioned air you're paying for just escapes into the attic.Tip #5: After you've cut your grille opening and sealed top/bottom/sides of the wall cavity, you might want to paint the inside of the opening a dark color - depending on which direction you plan to adjust your louvers, when looking up or down, you'll be able to see the gorgeous alteration (i.e., mess) you just created when you altered the studs or rigged it with whatever material you sealed the cavity with. A darker paint color (and if you created nice seams with caulk), will prevent seeing that unsightly job when your grilles are installed and you're looking through them.Overall, I'm more than satisfied with these transfer grilles, we've noticed a considerable difference in air flow, temperature and comfort in the rooms (note, we do have ceiling fans in the rooms, but before installing the air return grilles, they were simply only stirring up the unconditioned air, dust and all, pressurizing the room, it is not healthy nor safe to be subject to those irritants). While they cannot replace actual ducted returns or balance the HVAC system entirely, they can and do provide a solution for those needing an alternative, or until they can afford retrofitting new ductwork in the future. If I could suggest an improvement, I would ask that they be sold in pairs with a slight reduction in cost for a paired purchase (because you need two for every opening you create).

This is solid metal and sturdy. Fits well. These types of air vent registers (vent covers) are great and allow for maximum airflow. This is great for a vent that is higher up on the wall or ceiling since you can see more of the vent tube than other types of vent covers. But that is why is offers max airflow. You do have to turn each bar in the direction you want the airflow, but again, that is why it has max airflow which is what I wanted. Two way or three way air vent covers can block up to 20% of the airflow. Again, this is great for a vent higher up on the wall or ceiling that you do not need to close or change the direction of the airflow often.

overall purchase good, its aluminum, sturdy along the edges and border, where it needs to be, comes with two long screws with white heads., the fins in the middle do move, use two hands to adjust if your going to. the fins in the middle are thick and wide giving it a nice look over traditional vents out there. easy to install, just know the measurement of the inside of the opening.DIY tip..... to prevent chipping or removing of the white paint on the screw, put some tape on the end of your screw driver to keep it from doing that.

I'm remodeling an older condo and this new HVAC Air Grille greatly improved the look of the over the old grill that had been painted too many times.

I purchased this to replace a stamped face grille more typically seen in a residential setting that was whistling. With this fixed bar design which is usually more often used in commercial settings, my HVAC return now sounds like a whisper. The adjustable louvers are a nice feature that is uncommon on a return grill. People here have stated the louvers are 5/8" apart, but on the 24" x 12" version I purchased, they are a whopping 3/4" apart. That's lot of airflow!Mounting screws are supplied, so this ships ready to install. Please note the stated measurements for these refer to the hole in your wall or ceiling. The outsider perimeter will extend a bit beyond that once in place. Also note this is not a filter grille, meaning it's not the correct design to buy if your filter is supposed to be placed right behind the grille. It's for applications where your filter is elsewhere. I highly recommend that homeowners replace stamped face grilles with fixed bar ones like these. Your HVAC system will thank you for reducing its workload.

Works well (no rust and easy to clean) at my beach house where salt air is an issue.

Super

All around great product as a replacement for original fixed return grill. Unfortunately due to the adjustable fins that also swivels on the center bar, the vibration of the fins causes a metal rattling noise at the center.This can may be remedied by a thin foam/cushion between the fin and the center bar so the metals does not make contact.
