We ordered this for a TrailManor RV. Even though it is a battery vent, it was used as an exact replacement for the water heater vent
Good price, Good communication concerning our order and fast shipping. Very good company.


Excellent vent cover. As advertised. Excellent quality and workmanship. Good price. Convenient buying. Good delivery time. I would buy again if I need another.

Its been a year and the vent cover works great. Good buy.

Right part, Easy order, Great price, Fast response and quick turnaround. Doesn’t get better.


Quick easy purchase and delivery. Quality product at a fair price. Thanks


Fast service. Great communication.


Can I have a little more plastic on it


perfect fit. Exactly what I wanted


This unit was a direct replacement for the original units which had failed due to sun damage. So far not issues with these units located on compartment doors in our horse trailer.


Low cost vent is good for interior applications in locations where impact is unlikely. I used one to ventilate ceiling space between panels in an RV. I installed one in a small sailboat locker and broke it a few days later. Not very durable and I suspect that sunlight would quickly degrade the plastic. For RV exterior I have found the stainless steel round vents to be much better.


Recently purchased a used 2002 Carri-Go by Dynamax, although in really great shape with few miles(33,000), as is common with used RVs, there were a few items that needed replacing....this cover for the battery exhaust was one of them...well being Newbies at the game of RVing....I had no idea of what I was even looking for, but when I hit upon and put in "outside vents" up pops exactly what I needed, after exhausting all other avenues at other sites. Placed order, could tract and arrived well packaged ready to install....will definately use again....thanks!!!


These vent covers were exactly what I needed. The old covers were cracked and discolored. The new covers helped spiff up the outside of our fifth wheel. The hardest part was removing the old covers and putty. Once I had it all cleaned up I screwed the new parts in place and re-caulked the edges. Wow what a change.


The old vent covers were broken and deteriorated. The new one are an exact replacement. They were easy to install and look as good or better than the original ones did when they were new.

No problems, so far.

I am so excited to find etrailer.

order was received in a very timely manner and the price was EXCELLENT!. The battery vents were exactly what I needed to dress my little palace up and keep her looking sharp and brand new.

The staff was very knowledgeable, friendly and helpful.

You will have all my business and I will be sharing your website and my experience with everyone I know.


The product was as pictured, affordable and good quality. It will cover the vents perfectly. I really like how your website is designed and the photos/ measurements allowed us to select the correct item. We were notified when the order was received and when the order was shipped. We will be shopping with you again. Thank you! You rock!


Great customer service! I wasn’t sure which product was right for my camper, so I emailed a picture and asked for advice. I received a very fast response, placed my order and received it all very quickly. I’ll use eTrailer for all of my needs. Thanks!


It's exactly what it says it is. Great replacement at a great price. It fit right in place of the old one.

Still Great after a year

Great product - more robust than the original, and all of the holes match up.


Again, this product was no where to found on other sites. The description of the

  • Will Valterra Louvered Battery Box Cone Vent Cover Work With Fifth Wheel Trailer Battery Box
    I went to the warehouse and took a measurement of the Valterra Louvered Battery Box Cone Vent Cover # A19-3300 for you. The mounting holes for this cover are 3-1/4 inches center-to-center, so it looks like this cover would work well with your battery box.

  • Vent Availability for Running Battery in Enclosed Trailer
    There are a lot of people who run batteries on the interiors of their trailers without problems. What you can do is install a battery vent like part # A10-3300 on the trailer and it would be vented. Ideally you would have the battery sealed in a box with only the vent as a way to get to air.

  • Battery Box Vent for Additional Battery on 5th Wheel Trailer
    We carry battery box vents that I've linked for you. However, we do not have the hose or additional connector that you're looking for.

  • What Would be Needed to Relocate RV Battery from Tongue of Trailer to Inside RV
    Moving the battery to the inside of the camper will get your tongue weight lower like you are wanting but it does require venting the battery box whether it's connected or not. You normally have to build an enclosure where you want it but we do have vent setups specifically for this with the Valterra Battery Box Cone Vent and Louvered Cover # A10-3300BK-05. This would install on the wall of the RV where you build the enclosure which will allow it to vent to outside as it's in use. Now...

  • Can The NOCO Battery Box # 329-HM426 Be Vented To The Outside Of A Cargo Compartment
    The Commercial Grade Battery Box for Dual 6V Batteries # 329-HM426 is a hard molded plastic so you could definitely cut a hole in the lid and run a hose from it to a vent like the Valterra RV Battery Box Vent with Cover - White Cover # A10-3300-05 ( # A10-3300BK-05) which can be mounted to the wall of your trailer. These vents fit 1-3/4" battery box hoses, which you would need to source from your local hardware store, and can be secured with hose clamps.

  • Vents for Sealed Battery Box In RV
    For venting a battery box to the outside of an RV we have the vents for the side of the RV with the Valterra Battery Box Cone Vent # A10-3300-05. That said we don't have a totally sealed battery box that will fit both of your batteries. We have boxes that could fit both of your batteries but the lids of them are vented so it would not be ideal for your batteries unless you were able to create a sealed room for the battery box. It looks like most people make custom enclosures for the batteries...

  • Fan and Return for Use in a SpaceKap or Camper Shell
    The MaxxFan Deluxe Roof Vent w/ 12V Fan and Thermostat - Manual Lift - 10 Speed - Smoke part # MA00-06200K that you looked at will be a great choice and will move a lot of air for you. As far as proper venting goes you can install a couple of the Valterra Louvered Battery Box Cone Vent Cover - Black part # A10-3300BK on your bulkhead between the cab and the bed this is a fairly protected area from road spray and dirt and such and is just a one sided vent that would allow plenty of flow....

  • Options to Vent a Storage Compartment on an RV
    I actually like your first idea better because we have trailer vents that you can install on your door to help keep water spray away from the internal components. Our selection ranges from battery box vents like part # A10-3300BK-05 to ventilator like part # PLR20 to wall vents like part # HMAV2-AVT2. These options will not only help to give you ventilation while protecting your solar setup from the elements but they will also help to give you a clean looking installation. I recommend installing...
