2-Piece Polypropylene Trailer Vent for 3" Diameter Hole - Black

by: Matthew E03/13/2017

Purchase was simple and shipping was fast. I placed the vents of the right and left side with little or not issues and sealed as per instruction. If I was to make a recommendation I would suggest placing a tube of sealant in the vent. But, then you may have issues with color, etc. for customers. 352124

I purchase 2 of these vent's a few weeks ago, Very easy to install. i decided to order 3 more , as they say more vent the better . The only thing i have a problem with is they don't come with screws. 361169

Finally found the time to install 2 of these air vents on my cargo trailer, putting 1 on each side about mid-length and up towards the roof. I used a 3" hole saw with a 1/4" drill bit in the center. I marked my spot on the outside and started drilling. Once I got the 3" started on the outside, I went inside and drilled the #' through the inside wall and kept going through the outside wall. The 2 pieces fit perfect. I then secured each piece with stainless steel screws. I took my time and things worked out great ! These vents should help remove a lot of the hot air that builds up inside of the trailer, here in SW Florida ! 580699

The product seems to be well made and I believe installation will be easy. The only down side is if you are installing it onto any surface that is not at least 1.25" thick, you will need to take up the extra space. This is usually not the case with a trailer wall but is in my case of a composite molded wall of a walk in storage pod. I recommend a finer screen be cut and siliconed onto the molded grate to keep out smaller insects but that is an easy upgrade. 224935

I bought a pair of these to vent my 6 X 10 cargo trailer. They worked great ! 431246

I have sold the trailer. While I did have it, though, the vents worked very well.

While it is just a 'through-the-wall' air vent, it is exactly as advertised and was delivered promptly. It was purchased for a small camper I am building. As others have noted, it doesn't incorporate a bug screen/filter, but anyone able to install the vent should be able to insert a screen if desired. I also plan to install a simple shutter over the inside part of the vent so that it can be closed as needed. 450747

Great price and work great too. 555012

Product was packaged very securely and delivered in a timely manner. I would definitely go to ettrailer for all of my trailer needs. I ordered a basic enclosed trailer. Purchased flush tie downs, stabilizer jacks and vents. Installed all items with ease with no special knowledge or tools. I saved around $450 should these items be included with the trailer. Now I have a sweet enclosed motorcycle trailer that I can use what's the all the amenities I needed. 369190

I have used your web-site before and find it very easy to navigate. The product I ordered is for a small, 5X10 trailer that I use to haul/store my landscape equipment. In the summer months, things get hot and stinky in the trailer so I ordered these to provide ventilation. Your company shipped these vents very quickly and they were no problem installing in my trailer. I have already bookmarked your web-site because it provides the equipment that I need. Thank you. 143013

Perfect!

Just finished installing my new vents, very easy to install and look pretty good as well, hopefully they serve they're purpose. Any ventilation is better than none. 413321

Easy to install. I just wish they came with an insert so bugs couldn't get through. I ended up using a window AC filter which worked perfectly for letting air through but making it so bugs can't. 426901

Another review (above) recommended using a plywood jig. I took their advice and was glad I did. They did not include images, so I am. It made the install SUPER easy. 1) Use a scrap piece of 1/2 or 3/4" plywood slightly larger than the exterior vent. Find center of plywood and use 3" hole saw to make opening. Insert the round interior vent (loosely) from one side, and then loosely attach semi-circular exterior piece. Pinch all three pieces together and set on a flat surface. Trace the outline of the semi-circular vent onto the plywood. Make marks at the 6 screw hole openings. 2) Drill through plywood at the 6 screw openings. 3) locate vent position on exterior of trailer (note: make sure the shape of the vent corresponds to the flow of air!!!). 4) place plywood jig at desired loaction (press against exterior of trailer) and drive at least 4 self-tapping screws through plywood and into trailer wall (make sure to use screws long enough to penetrate thickness of plywood). 5) now that plywood is attached to exterior of trailer, use a hole saw to cut through metal and plywood interior wall. The jig will keep your saw in perfect path. 6) Apply silicon to inner rim of 3" round interior vent cover. Press into opening. 7) My interior vent was the perfect depth - It was flush with exterior of trailer wall. If yours is too long, cut to proper depth. Apply silicon at seam where metal opening meets end of interior vent (added protection against rain). 8) Add silicon bead on underside of exterior vent flange. Align with screw holes (from jig attachment) and drive 6 self-tapping screws. Good luck! 240227

Excellent product and easy to work with. Great service. I was concerned however about insects entering through the vents so came up with a filtration system. Used a PVC coupling and some filter material. Cut the coupling to 1/2 inch rings and remove just enough material to allow an inside press fit. Cut round filter and insert first then hold in place with the ring. On the outside vent cut a long narrow piece as shown. When installed as shown, adds very good double filter and allows air to move freely. Just finished a 6000 mile trip clear across the country and back and filter performed perfectly. Eliminating the heat build up AND keeping the bugs out. JIM : ] 102260

Just what the pic shows. Bought to ventilate snowmobile trailer. Not installed yet, but will definitely help . Trailer only came with one vent that was pretty much useless. Good price also. 29791

We use these on every trailer we make, very good heavy duty vent, attractive, adds a design element to the trailers. We use both black and white vents, depending on the side color of the trailer. Yes, we are kind of trailer nerds! And we do love e-trailer! 524150

We use these in all of our trailers, they work just fine, we have had no issues with them. They just provide a little extra ventilation. We use them as a wall vent with lots of silicone behind the screws, and have had no issues with water infiltration or insects. One of our go-to products. 564958

Product arrived as described. Awaiting trailer delivery then it will be installed. In the mean time I made filters for both sides to keep the insects and dust out of the trailer. Only down side, no screws were offered with the product so I went to Lowe's and found some white aluminum ones, sanded the white paint off and painted them flat black to match the vent. 126274

I did not go wrong buying this item. Very good for venting tight closed compartments. 630831

Nice vent- wish it was available in the color White or Silver like my custom build. 583549

Purchased item for venting 5X8 enclosed trailer. The item was positioned front and top of the side wall and mounted with venting facing forward. Two additional 3” floor vents were installed in the opposite end of the trailer to allow air flow. Hardware is not included with item; the air flow is restricted by the nature of the water proofing design which restricts the flow to less than 40% of the 3” diameter opening. 548146

It should provide a little more air flow for the m/c trailer. I added some coarse filter material to keep out bugs. 540109

The outside finish has witness marks from the molding process. I’m sure it will work good. Low score for finish 525117

works as expected 521937

Bought 2 of these to vent my trailer. Extremely simple install. Just use a 3" hole saw to locate the inner vent, center and level the outside vent and use the holes on the outside vent to mark the hole pattern and pop some pilot holes for the screws. I used some sealant around the flat that sits flush to the outside of the trailer as well as around the inner vent on the outside of the trailer. 517443

Good quality air vents for an enclosed trailer and very good experience buying them from etrailer.com! 495500

I installed this in th sidewall of a cargo trailer, along with a solar vent on the roof, also found on this website. It's a simple design and it should work as advertised. It would get 5 stars if it would have come with the hardware to install it. I used pop rivets and they worked well. 494981

We were very pleased with the durability, look , and installation of the vents. We will use use your website again. 485232

Good product, easy to install... just make sure you are not cutting into hidden support structures. So far, I can see a big positive difference in the amount of moisture in the trailer. The vents do help. 468606

Those parts that we purchase from etrailer always arrive as advertised and in a timely manner. The parts (we are a teardrop trailer manufacturer, and are notoriously hard to please!) are sturdy and well made. Have never had an issue with this company in the four years we have used them as one of our suppliers. 466261

Product was good order arrive quickly and price was great. 441781

It was exactly what I needed to replace one that was damaged on my enclosed trailer. The price was right. The shipping was fast. It was a perfect fit. Nuff said...except, thanks so much for being there when I needed you!!!!!! 440987

Extremely prompt service from ordering to shipping. Great communication for my order confirmation, tracking number, and follow-up. These vents are exactly what we were looking for and actually shipped more quickly than I thought they would. Would definitely recommend etrailer.com to others looking for parts and would order again. 439891

Very pleased with Vents.... very easy to drill couple holes and install into our Community Emergency Response Team's Supply Container... 412629

Maybe could be harder plastic. For now works as expected. Thank you for your excellent service. 410822

Easy to install and made a BIG difference in the inside temp. 396861

I ordered two of these vents for my horse trailer. They have helped a lot with the heat and humidity build up in the tack area. The only problem is that they are plastic and paint does not stick very well to them. I tried to paint them the color of my trailer but the paint does peel off after awhile. I think I will just let them be black from now on it is easier. Other wise a great product. 391799

by: Dutch03/13/2017

Good quality product. I installed two of these in a small cargo trailer. They are very sturdy and haven't leaked a bit since install. 355957

Seems to work good. I used on my hibrid snowmobile trailer hope this help keep the condensation out. 349533

Great vent, used to vent the floor under norcold cooler on a teardrop trailer. Easy install 345979

Vent was easy to install. Installed 3 on my trailer in under an hour. These will provide air flow when I am traveling and in the summer when temps are hot. 333615

Got them for my 20' car hauler. Quick delivery and exactly what I expected. 330599
