Video Transcript for Polar Hardware Enclosed Trailer Parts - Vents - PLR1715 Review

Today we're going to take a look at the Polar Hardware side cowl ventilator with the screen. This is made of a 20 gauge cold rolled steel construction. Has a nice zinc plating for corrosion resistance. This can be a weld on or rivet on installation. We're going to give you a few measurements on this and just to show you how this operates, you can see the lid is open. That's with it closed.

And this handle right here, if you just push down on it, will open up the vent. Just pushing down like that. And you can see the vent will open. I do want to give you a few measurements. We'll start with just the lid itself. The measurement on the lid length is going to be right at 10-7/16" and the width on it is going to be right at 5-3/16" and then on the whole mounting flange itself, from end to end, is going to be 11-5/8" and the width is going to be right at 6-15/16". But that should do it on the review of the Polar Hardware side cowl ventilator with the screen..

Side Cowl Ventilator with Screen - PLR1715

Average Customer Rating:  3.3 out of 5 stars   (4 Customer Reviews)

- PLR1715

Item was moderately easy to install. Drilled and riveted instead of welding to metal. Screen doesn't protect well due to cut-out for door lever. Works good all in all. Nice to have extra ventilation when needed. 410389


Still working well. Thanks

I have not figured out how to mount this product. The flange for mounting is very narrow especially around the hinges for the vent door. The product does not come with instructions of mounting so you are on your own when it comes to mounting. I did not have the guts to cut out a hole in my trailer to figure it out. There may be smarter folks out there that have figured it out - unfortunately I am not one of them. 674830


Polar doesnt include instructions because there would be many different ways to install the ventilator, which would vary according to the trailers wall thickness and the material the wall is constructed of. Polar recommends either welding or riveting the ventilator in place.

  • Side and Roof Vent Options for 5 x 8 Enclosed Trailer
  • We carry all sorts of trailer vents and we can help you with a solution to provide proper ventilation in your 5 x 8 trailer. You can use either a roof vent or a side-mount ventilator, or both if you wish. We offer two side-mount ventilators that offer passive air flow, parts # PLR1715 and # PLR20. Side Cowl Ventilator # PLR1715 includes a screen and measures approximately 6 x 11-inches. Ventilator # PLR20 measures approximately 10-1/2 x 12-inches. Both vents allow you to open/close air...

  • Recommended Wall Vents and Roof Vent for Enclosed Trailer Air Movement
  • The Multi-Purpose Ventilator - Aluminum # PLR20 will work to help you move air through your trailer. You may also be interested in the Side Cowl Ventilator with Screen # PLR1715. For the best air movement and still the weather protection, I recommend these side vents for the lower vents and then using a roof vent like # MA00-06401K if you have a trailer battery. If not, then I recommend the Ultra-Fab Solar-Powered Plumbing Vent for Motor Homes - 7" Diameter x 3-3/4" Tall # UF53-945001...

  • Installation Of Polar Side Cowl Ventilator with Screen # PLR1715
  • The Side Cowl Ventilator with Screen, part # PLR1715 is really not designed for a travel trailer application. This vent is made to be used for an enclosed trailer that normally has an outer wall the vent is mounted on and access to the vent from the inside. The vent can be riveted or welded on. I recommend using a silicone sealant when installing the vent so you can prevent water from getting inside the trailer. The mounting flange measures 6-15/16 inches x 11-5/8 inches and the...

  • 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...

  • Recommended Vent Setup to Cool Enclosed Trailer Mobile Workshop
  • Even the smallest RV air conditioning units we offer will require 115-volt AC electrical service of at least 11-amps to operate properly. The Atwood Air Command Rooftop RV Air Conditioner # AT15025-21 will draw almost 4000-watts at startup and even once running it will still need close to 1300-watts to operate. Delivering this amount of power via high capacity 12V batteries and an inverter such as the 5000-watt Go Power # 34280179 will be a fairly costly and bulky proposition. Instead...

  • Available Trailer Sidewall Vent Covers
  • We carry a range of complete trailer vents for roofs and walls as well as many replacement parts that you can see on the linked page. From your description it sounds like you may need both a side ventilator like Polar Multi-Purpose Ventilator # PLR20 (12-1/4 x 10-1/2) and a Side Cowl Ventilator # PLR1715 (6-15/16 x 11-5/8). As you can see these items do not have the exact specific dimensions you are looking for. These are not intended for any one particular trailer type or brand so they...

  • On the linked page you can view all of our RV kitchen range hoods. All of these vent to the outside through a damper-less vent. Please note these come in various sizes so you'll want to compare your range hood dimensions. We have stainless steel models like the 24 x 12-inch Ventline # S0721-24GC-F-1 as well as black and white models too. Just click on your size and color preference. The hoods have an exhaust port that measures 3-1/2 x 9-3/4-inches so you'll need to create an opening...
