This 2-piece vent provides an inexpensive yet attractive way to ventilate your enclosed trailer. Round interior vent and half-moon-shape exterior piece are both constructed of black, UV-resistant polypropylene plastic that holds up to sun exposure.
My 5x8 enclosed trailer was overheating due to no arrangements for ventilation. I added the 2-piece polypropylene trailer vents along with a rooftop solar powered plumbing vent and my problem was solved. The inside of the trailer temperature remains pretty much close to ambient temperature
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 : ]
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!
We use two of these vents on every trailer that we make, and are nothing but happy with the condition, the price and the functionality of it. Such a simple concept that just works so well for some additional ventilation.
Ticks all of our boxes for passive air flow. Have been using them in our trailers for years now. We use two per teardrop, one on each side of the trailer for cross ventilation.
Not so Impressed. There doesn't seem to be much better airflow in my trailer. I installed 4 vents. The way the product is designed seems to block air from coming instead of letting it flow.
Mirabify - 07/27/2020We 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!
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.
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.
Easy to install and doesn't allow any rainwater to get in. Good product!
I needed a rainproof vent for an outdoor electrical equipment box (WiFi). This item fit the bill perfectly. It's mounted on outside of box and an exhaust fan is mounted over the 3" hole on inside. Only used the interior vent as a guide to line up exterior part with 3" hole. Glad I ran across this item while searching for a vent and eTrailer gave quick shipment.
RussB - 08/01/2015Just 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.
No complaints. I'm not sure how efficient the air transfer it through this vent, but it was easy enough to install, and has been water tight. It's installed to vent my battery compartment through the rear of my teardrop trailer.
very good quality, easy installation, I have bought for another install already.
Bryan - 09/23/2020Vent, easy install, nothing special, it's a vent.
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 !
Great product! Installation was easy and straightforward. I would definitely recommend it!
Easy ordering. Fast delivery. Web site easy to use. Highly recommend shopping through etrailer.com
My trailer is light weight easy to pull, even loaded don't even fell like its there . The only issue i had and still have the travel lights don't work properly, Ive check the power plug on my truck got a new adapter . I had my dealer ship check its not the truck or plugs. Its some were in the walls of the trailer i really don't want to take apart the walls travel lights to me are not that importation just tail, and break lights im good with my trailer.
Great Product.. Great to do business with you company. They are already installed. Very Pleased, I will do business with you again.
purchased a 5x10 enclosed cargo and will be installing 4 vents that are at a great price and will keep my trailer at a lot cooler temp, Thank You etrailer for the speedy shipping, and great parts.
Rigo V - 10/01/2018Product 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.
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.
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.
