Features to know about

Adjusts Airflow with Twist Knob: Controls Heating and A/C Flow

This ceiling vent makes it easy to dial in just the right amount of warm or cool air. The built-in knob opens or closes the dampers so you can fine-tune airflow without tools or extra parts. It’s a simple way to balance air across different areas and keep every spot comfortable.

Fits Standard 4" Duct Openings: Quick Wall or Ceiling Install

Designed for 4" duct openings, this vent mounts cleanly to either a wall or ceiling. The included hardware means you can swap out an old vent or add new airflow points without a hassle. It’s made to fit tight and sit flush so the install looks neat and finished.

Clean, Finished Look with Snap-On Grille: Hidden Mounting Hardware

Once the bezel is in place, the grille snaps over the top to hide the screws for a smooth, finished appearance. The off white color blends in easily with most interiors, keeping things simple and tidy wherever it’s installed.

Durable Off White Plastic Build: Long-Lasting and Easy to Maintain

Made from sturdy plastic, this vent stands up to everyday use without cracking or warping. The smooth surface wipes clean easily, and the neutral off white finish keeps it looking new over time.

Compact Dimensions Fit Tight Spaces: 5-1/2" Diameter x 2-3/16" Deep

At just 5-1/2" overall diameter and 2-3/16" deep, this vent fits snugly even where space is limited. Mounting holes are spaced 3-3/4" center-to-center for a secure fit. It’s a straightforward, reliable way to keep air moving where you need it most.

Video Transcript for What to Know About the Valterra RV Ceiling Vent w/ Adjustable Knob

Randy: Hey guys. Randy here at etrailer.com. Today we're going to be taking a look at an AC register heat vent from Valterra. This one I really like. I think it's got a lot going for it. Basically we have the option to rotate the vent in any direction.

That's going to direct the airflow where we want it to go. But also we've got a knob here. We can open and close that. I think this is a really good idea and I think it's a great design. Not only do we get to get the air in the direction that we need it the most, but we can shut it off when we don't need it.

Basically, if we're at nighttime, maybe we're sleeping back in the bedroom, but we need the heat, we don't necessarily need to heat the whole RV. So we can shut a few of these off and be much more efficient than what we would if we we're trying to heat the whole thing or in the summertime when it gets hot for running the air conditioner, we want to cool certain parts at certain times.So out here during the day in the living quarters and then back there in the bedroom at night. I think it'll just help out a lot when you're on the dry camping, when you're out boon docking. If you're plugged into shore power, it doesn't make that big of a difference I guess. But overall I think as far as being able to open and close it, it's one of the simplest ones out there and as far as being able to direct the airflow, just works really well.

All right, for the replacement process of course we need to get our old vent removed. You can see this is the type that spins all the way around the outside there. It has a center push pin. Now they can be varying in tight. But most of the time you're just going to have a cover on the outside that kind of protects and covers those screws, makes it look nice.

So in this one we want to pull out on both sides here. I'm just going to gently wiggle it side to side.You can see that center section is going to come out and there we've got our four screws. A lot of times these are going to have a square bit. You can see there's a square in the inside. But a Phillips will also work for it. Let's just get this taken out, just going to be kind of like wood screws there. Not much to it. Then we'll pull that out. You can see there's our ducting material just like a dryer hose really. You just kind of want to pull that out and to begin our installation, we just need to slide our vent to over the back of the vent here. Get it on there as far as you can. Sometimes you can gather up a little bit of extra and slide it on there just depending on what you've got to work with. Once we get it in position there, I'm going to reuse our existing hardware. You can also use the hardware that comes with it. We'll just get them lined up and secure here. All right, at that point, you can see our vent's ready for use.We can direct our airflow where we want it. We can also open and close it for when we want air and when we don't. So as you can see, really easy to install. It doesn't take any more or any less time than a lot of the other ones out there. I guess the only negative I really see about it is there's really no cover for our screws. We're reusing our original screws. It's also going to come with a set of screws if you want to use those. So that would be my really only negative thing is you see a couple of screws. But outside of that, it's definitely one I would like and something I would replace my vents with.

Vent is less than I expected. Too loose to keep adjusted

The vent covers have worked well. Very stable and great for keeping the rain off of the vents so that they can remain open when it’s raining.

@Daniel Glad to hear it Daniel. No venting about these covers—just smooth sailing, rain or shine! Any fun trips planned for the year?


by:

Worked and fit as described. Was nice to have control of the air flow in our rig.



by:

After ordering, they told us the vents were on back order and would not be available for about a month. They arrived within a week. They fit perfect and look great. Nice job!



by:

Perfect fit, works well.



by:

It would be nice if you offered this in white. Our walls are white and beige is a poor match.



by:

Looks like exactly what I need for my RV heating system. Thank you very much. I'm going to try it out and I'll let you know.



by:

The vent registers arrived in good shape and fit perfectly. Thanks again. Your follow up is amazing!



by:

We have always had good luck ordering from 'Etrailer'. They ship promptly and usually have what we need. This item was a perfect fit.



by:

Shipping was fast and it was a perfect fit. Etrailer is a great place for parts.



by:

The pressure from the furnace keeps closing this adjustable vent, so it really isn't functioning as expected.



by:

This was a perfect replacement for the OEM one that was in my motorhome. The screw holes even lined up. The only issue I have is that it wont stay open. I can set it to open and sometimes it will stay that way until the furnace cycles off then comes on again. It always gets blown closed. But most the time, I set it open and it will be blown closed by the furnace air within a minute. This is the closest register to my furnace so the air is coming out full blast. I'm ok with it because that register will be closed 99.9 percent of the time anyway.

by:

These are OK, I needed these to operate at an almost closed position but they are not tight enough on the gear to hold the flaps back at an almost closed position, instead the air pressure would just force it closed.



by:

Looks great, easy install, control mechanism bad design. I bought this to replace a furnace vent in my 5th Wheel bathroom that had one that was not adjustable. This one is adjustable, BUT the force of the furnace air causes the vent to close all the time. Since my bathroom is small that's exactly what I wanted but would have been nice to be able to open vent when needed, it just won't stay open. I have solution by using toothpick to wedge adjust knob at position I want, but this is not ideal. Not sure if it's just high air pressure or any air pressure that will cause it to close.



by:

Fast shipping, part as described. Switching a dampened control in the bedroom of our motorhome. Worked perfectly

It was purchased to reduce heat flow in the bedroom. Has done just as I wanted. Keeps it cooler in the back and directs more flow to the rest of the motorhome. Recommended.



by:

Delivery was quick and easy. I love the communication for every phase of the order. I think etrailer is the best at communicating status! Installation was simple and took about 5 minutes to replace the oem vent cover in my travel trailer.

These are great for controlling air flo w.

As are you Gerardo =)



by:

Good product. Sometime the vent shut close from the force of the heat. I wish it comes with a matching color screw.



by:

Just what i was looking for, thanks!



by:

Not impressed with the slow shipping and that there wasn’t a good way to track shipping. I got an email from Amy when the part arrived, but that was it.



by:

Valterra makes good products. Our new 5th wheel toy hauler came with non-adjustable heater vents and the bathroom and the bedroom would be hot but the kitchen/living area would be cool. I got these to replace those heater vents it came with so I could close off the bathroom and bedroom and force more hot air to the kitchen/living area. These adjustable vents make that happen very efficiently. Shipping was fast and well packaged, installation is simple and these accomplish exactly what I had hoped they would accomplish.

A year later and I am very pleased with the operation and design of these vents and they are still working as designed. No issues with the openclose adjustment knob. They have stayed in place even after towing the trailer on some very unkept roads and highways. I highly recommend these vents.



by:

exactly what I was looking for the A/C in my boat. See etrailer for all your RV, Boat, or Off-Road needs, they deliver as promised.



by:

The product itself was exactly what I needed. There was a problem with one of the vents, the control knob was defective. Etrailer promptly sent out a replacement. Excellent customer service!

  • Color Options For Valterra 5 1/4" Diameter RV Vent Ceiling Register
    There are a few other colors than the off white that the Valterra RV Vent Ceiling Register - 5-1/4" Diameter # A10-3349VP is offered in that may interest you. The closest color to a light brown would be the Beige # A10-3351VP but we also offer Brown # A10-3352VP, Black # A10-3353VP, and standard White # A10-3350VP. I included a video of the Valterra RV Vent Ceiling Registers for you to take a look at.

  • Is the Valterra Heating and A/C Vent Register A10-3350VP Air Tight
    The Valterra Heating and A/C Vent Register part # A10-3350VP like most vent covers is not completely air tight. There will still be a bit of air that can escape through the vent while closed. This is very common for duct work either in a home or RV. If the above vent is not as air tight as you would like then you may want to consider a different style, the Valterra Heating and A/C Vent Register part # A10-3349VP which has an off white color but will form a better seal.

  • Availability of White 4 Inch Heating and A/C Vent Register
    The exact model Valterra Heating and A/C Vent Register # A10-3349VP that you referenced with the small knob at the center is not available in white but we do have the extremely similar Heating and A/C Vent # A10-3350VP in this color. This is designed to fit the same 4 inch diameter vent hole as the Off White unit you were looking at and the installation hardware is included. I have attached a short video review that you can check out as well.
