I have installed several return air pathways that go through walls, which help a lot in allowing the air conditioning to continue to work in rooms that have their doors closed. I bought this for a room where the studs are too close together and I have electrical and pluming issues where I would like to put a normal return air pathway. This door version is actually cheaper and probably easier to install. For this to be an easy project, you should have a jigsaw, but you could probably make it work with other tools if you were dedicated. If you are like my your doors are basically hollow with only thin walls. That makes them easy to cut and this fits right over the hole. Very little light and noise gets through and it looks pretty good installed. It makes a big difference in the air flow. This extends your door downward a quarter of an inch or so unless you chisel away some of the wood at the edges so it fits all the way in. That's what I did and it's a pain because my doors are made of very flimsy material. I ended up putting some caulk around it as well to act as a makeshift glue of sorts. In other words, because this attaches by only two screws at the bottom and because doors are made of really weak stuff, this isn't very securely attached if you don't also use some kind of glue. This is also made of plastic and cardboard. It wouldn't stand up well to being kicked or something. Just be aware of that when you are deciding which doors this is appropriate on. Having done both, I'd say cutting the door and using this is easier than cutting the drywall and making a hole in the wall for the other type of return air pathway. I recommend them both, but this is the easier and slightly cheaper option. Review: Fits great, looks great and works great - We have an addition we build over our garage (huge bedroom with a tray ceiling) and the HVAC guys put the air return at the top of the room when i told them I wanted it at the bottom. (Long Story) Ever since that, in the winter time if the door to that room is closed, it becomes a walk-in freezer. This vent solved that problem. The room is now the same temp as the rest of the house because the cold air that was trapped in the room can now escape through the vent. Installation was easy using a jigsaw, but I have 1 suggestion. when you trace out the pattern, cut the small vertical ends directly or slightly inside the traced line. I went a but outside of it and there was a bit of extra space. if I didn't center the vent, you could see a gap. So, cut inside the lines a bit and if its too tight, you can always remove more material, you can never add more back in. Installation took maybe 20 minutes total from removing the door to putting it back on the hinges This worked fantastic, I couldn't be happier ## Features - QUALITY AIRFLOW – Save time, energy, and money with a Tamarack transfer grille.

Then I realized that they’d be terrible to try to fix into a hollow-core door, and they wouldn’t be able to dampen the noise of the furnace. The room is next to my den/movie room/exercise space, and near two bedrooms. It would be really annoying if there was a lot of noise. I don’t know how I saw this one first; I think I came across it on YouTube when looking for something else. It installs so easily into a hollow-core door, is simple to cut out with the template right on the box, and even includes two screws to attach it with. (Would have been nice to say what size holes for the screws... I wasn’t convinced they wouldn’t strip without at least a starter hole.) I took the door down, carried it outside, and finished the cut, install, and cleanup in half an hour. That only took me that long because I don’t have a full sized circular saw, just a mini, and had to flip the door over to cut out the other side. I used an oscillating multitool to make the long cut through the hollow core, just because I needed it for the initial plunge cut, and found it to be easy enough without switching back, but either would work. I took off a star for two reasons; one, the inside sound dampening baffles are made of cardboard, and they’re not sealed into the plastic all around, so I wonder what will happen if they become damp. For a device that costs this much, I expected something more sturdy inside, perhaps a foam based baffle. The other reason was the cost; it was $41, which was too much for a piece of molded plastic. But it did work, and I made up for the cost by doing it myself—contractor wanted $300 to do it, though he’d supply the vent. ## Frequently Bought Together - Tamarack Air Transfer Grill, Off-White, 27 1/4in.W x 4 3/4in.H x 1 5/8in.
