Video Transcript for Polar Hardware Enclosed Trailer Parts - Vents - PLR24-004 Review

Today we're going to be taking a look at the butterfly vent and gasket from Polar Hardware. The butterfly vent is going to provide ventilation for your trailer, or whatever it is you'd like to install it on. This can also be used with the Polar roof ventilator. Model PLR24. The unit's going to be made form aluminum lightweight construction, that's going to be highly resistant to rust and corrosion. The vent is going to include this nice little gasket here.

What that does, is it creates a nice tight seal at the mounting location, and provides some cushion, at the mounting location. The unit's going to give us a diameter measure from outer edge to outer edge, of 7 1/4 quarter of an inch. The mount holes, these are going to be separated on center going this direction, by 4 9/16 of an inch. If we take a measurement straight across, those are going to be separated on center by 6 1/2 inches. Your mounting hardware is not included, so that is going to be sold separate. The mount hole diameter, it's going to measure right at a 1/4 of an inch.

The opening, so from this edge to this edge right here, that's going to give us an opening measurement. Looks to be 5 11/16 of an inch. If we take a look at the measurement we have from the edge of one blade to the edge of the other, that's going to measure 5 7/8 of an inch. This is not a waterproof design, it's not a waterproof vent. We recommend installing it on the side of your trailer, with the openings running front to back or parallel to the ground. It would be just mounted like this.

Like I'm showing it to you now. This mounting option will be the best position, for keeping out the most amount of moisture, if your in a situation where this is exposed to a lot of moisture. It's got nice and easy operation. The vent opens and closes very easily, and again it's aluminum, so it's got that nice lightweight design to it as well. It's highly resistant to rust and corrosion.

That's going to do it for today's look at the butterfly vent and gasket, from Polar Hardware.

Fits perfect!


Converted a propane grill into charcoal. Needed that venting system.......found the perfect part. Can finally control the heat and let some of the smoke out with this vent.


The air vents were just what i expected. I will be using them to channel air into my horse trailer during the summer months. In winter or inclement weather i will be able to close them when traveling/


High quality and great price.


This is just what I was looking for at a good price. The gasket is helpful for a better seal. I'm actually using it in my house as a seasonal airflow change to the main AC duct.

  • Recommended Vent Covers for 6x12 Cargo Trailer Hauling Animals
    To close the inside of your vents, I recommend the Butterfly Vent and Gasket for Polar Roof Ventilator - Aluminum # PLR24-004. These are 7-1/4 inches in diameter to allow you to mount them over the inside portion of those vents. There is not a specific part to close off those vents, but these will work well to take the direct air flow out of the equation when you don't need it. These ventilators will allow you to determine what air flow is needed for your cargo to keep them comfortable...

  • Availability of Butterfly Type Trailer Vents
    We do indeed offer trailer butterfly vents, as well as other types, and you can see items # 371800, # PLR24-002 and # PLR24-004 on the linked page. I also linked our main page for all trailer vents and vent parts. We carry replacement parts for many of the vent products we offer.

  • 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.

  • Trailer Tongue Box for Battery Storage
    The DeeZee Specialty Series Trailer Tongue Toolbox - A-Frame - Plastic - 6 Cu Ft - Black # DZ91717P is not designed for battery use. it isn't vented for that use so if you choose to use it in that way, you will want to add a vent so you don't have issue with the gases produced under normal battery operation. You could use the Replacement Round Interior Trailer Vent for 3" Diameter Hole - Black # AVT2, # PLR24-004, or something similar to add that feature and then you'd be all set.
