I purchased 2 for a horse trailer. I cut out only the butterfly to make it stronger and after 1 year, around 1000 miles, everything is still perfect. I do recommend them. 640594

I ordered 3 butterfly vents and received them very quickly in excellent condition. Shipping was very inexpensive, I was impressed. I do wish though that a gasket could be bought for that vent like the higher priced vents. 564395

These butterfly vents were replacements on a 1994 horse trailer that we are refurbishing. The old ones were solid rust and couldn't be saved. Though today's vents aren't made as large as the old ones, we can make them work and are good quality for this job without a huge investment. We're waiting to install until after we repaint the outside of the trailer so no photos at this time. Fast shipping was also a plus. Thanks etrailer!! 480237


Comments
The vents were great quality for what we needed to finish out the trailer for resale. Though I cant attest to how theyre holding up since we sold the trailer, I assure you we wouldnt have added something that we werent positive would hold up for years.

Ask the Experts about this Redline Enclosed Trailer Parts

  • Differences Between Butterfly Vents Part # 371800 and Part # PLR24-002
    The only differences between the vents is that part # PLR24-004 comes with a rubber gasket and part # 371800 does not. The mounting holes are also positioned a little differently. They are both 7-1/4" in diameter and made of a polished aluminum. If you are concerned with rust then I highly recommend using the Butterfly Vent part # PLR24-002 which is made of stainless steel.

  • Is the Butterfly Vent Waterproof and Will it Stay Closed or Open
    This Butterfly Vent # 371800 that you referenced is not waterproof. If the vent was on the side of the trailer it would not get direct water sprayed at it when it is raining so it should not let too much moisture through. If you left the vent in either the open or closed position it would move. The amount of friction in the vent assembly would prevent it from moving just from the vibrations of the trailer rolling down the road. With that being said, it is not difficult by any means to...

  • Side Vent for Enclosed Trailer with Interior Wood Paneling
    You can still use butterfly vent # 371800. The wood paneling in the trailer should not be an issue because no matter what material is on the inside you would have to cut a hole for the vent. If there is a gap between the outer and inner walls of the trailer then you could bridge that gap with some small gauge sheet metal such as tubing used for clothes driers. A vent such as # WHMAV2-WAVT2 might be a better option. I have linked a video review of this vent and the butterfly vent as well. I...

  • How to Install the 7-1/2 Inch Round Butterfly Vent # 371800 on an Enclosed Trailer
    To install the 7-1/2 Inch Round Butterfly Vent, # 371800, you will need to drill or cut a hole in your trailer that is 5-7/8 inches diameter to no more than 6 inches diameter. If you have access to a hole saw this size for a drill the wold be the cleanest way to cut the hole. A smaller hole could be used, but the butterfly may rub on the trailer sides if a smaller hole is used. The mounting holes on this vent are 4-9/16 inches on center and the distance between the inside of any two...

  • Installation of Redline Butterfly Vent # 371800
    On the Redline Butterfly Vent, part # 371800, the location of the nob does not really matter, usually on either side. We recommend to install the butterfly vent on the trailer so that the triangular openings of the vent are parallel to the ground, with one triangular opening to the front of the trailer and the other triangular opening to the rear of the trailer. I am including a link to a video review of the vent and in the video he will be holding the vent the way we recommend to install...

  • Recommended Vents for 10 x 20 Foot Shed
    The only vents we have that will work for the shed walls are manual open and close. The 2-Piece Side for Enclosed Trailers - Metal - 10" x 12" # 9139 is the nicest option and will close from the inside for the winter heating. You can use the butterfly vent # 371800 on the exterior if you so desire but it gives you not interior help. The Side Cowl Ventilator with Screen # PLR1715 is the option I recommend because of your desire to open from the outside. This has a gasket for a nice...

  • Venting a Sprinter Cargo Van to Keep Interior Temperatures from Climbing in Summer
    The Redline 2-Piece Polypropylene Trailer Vent # HMAV2-AVT2 that you referenced is a good option for your application in the summer time, but this vent does not allow you to seal it off in the cold months. A good option for your application is a butterfly-type vent that will allow you to open and close the air flow as required. Redline offers their round butterfly vent # 371800 that is shown in the linked video. This vent will withstand highway speeds but do note that there will be some...
