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.

Needed aluminum vent covers to reduce condensation issues, so these will do the job. They are also low restriction, which is good in terms of quiet airflow. The only issue is that two of the three I purchased had bowed louvers, and they were thin, so had to be very careful straightening them so I wouldn't damage them. For the money, I wish they were a bit heavier, but they will work fine. The paint job was the best I've ever seen on vent covers.

Home was built in the 1940's and had old ugly vents. Built oak housing and used this grille to update the look and function. Beautiful.

Perfect. Adjustable louvers. Thank you.

Quality product, is mostly all aluminum, as advertised, and painted white so shouldn't rust. It appears that the corners are actually steel (probably for greater strength) but you'd never know unless you held a magnet to it. Everything looks seemless. My only complaint would be the price. I can't believe how expensive a simple grill has gotten. I remember when you could get grills like these for about $10.

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 great but you will need to drill new holes

It looks ok

I had a grill over a small return near the furnace (for years) in an unfinished basement, and when it came time to finish it, we were looking for a solution to quieten down the return. You could hear the furnace / compressor through the duct, plus the grill made quite a bit of noise. A friend (who owns an HVAC company) added sound deadening liner inside of the first few feet of duct, which made the furnace noise much better, but the duct became effectively smaller (~7" x ~13" instead of 8 x 14 due to the liner, so the velocity through the grill went up, and the grill noise was even worse. I opened the louvers in the grill, but it looked like crap and only helped a bit.This grill, by comparison, is REALLY OPEN. There is no aerodynamic noise, even though the flow through this opening is quite high.The louvers are independently adjustable, but for now I have them all wide open.

We live in a house that was built in the 40s and was unfortunately never taken care of until we moved in. Some of the old style vents were so badly rusted and bent, and had been repainted so many times that they were not salvageable. We opted to to for something that didn't stick out from the wall as far and that would blend in. This part of the wall has a vent on each side which is why you can see through it in the pic.A cinch to install and a nice cheap upgrade to what we had there before.

I replaced a standard $10 air return metal plate that was generating a lot of noise (too much air volume flowing through that duct) with this 14x8 adjustable grille. The wind noise is gone. Yes it is 4x the price but it is much better build than the regular grille you find in the hardware stores.

As a HVAC technician in a small town RTA grilles are hard to find. This is a higher quality product then you would find at a hardware store. Much better free air flow then crappy plastic grilles.
