Video Transcript for Review of JR Products RV Vents and Fans - Plumbing Vent - 37202-29125

Today, we're going to take a look at the JR Product's white mushroom vent.Now this is a mushroom style plumbing vent that'll replace an older damaged vent. It's a very low profile. So it does reduce the risk of any damage in areas with low clearance. And it can be used for any ventilation application.It is a nice, lightweight, durable, plastic construction. A nice white color. And it uses the secure screw on cap to prevent loss.

I just unscrew it. And once the caps off there, you can see your ventilation. And you do want to remove the cap prior to installation and face the vent properly to prevent leakage. You can see right here, it indicates front. So you do want to make sure that's pointing towards the front.It does include the stainless steel hardware to install it.

You can see it has the four holes here, It comes with the four screws.And then just to put your cap back on, get it started on the . And it screws and tighten it right down.A few dimensions on this, the overall diameter from edge to edge is right at five and three quarter inches. The vent opening diameter measures four inches. Overall height on this unit is going to be right at one and seven eighths inches. And the distance on the mounting holes, center to center, straight across is going to be right at five and three sixteenths inches.

And same on those two.But that should do it for the review on the JR Product's white mushroom vent.

These attic vents were the perfect replacements for my old cracked and broken OEM vents. “etrailer “ had these in stock and shipped them right out. Thank you for your continuous supply of RV parts and great customer service and support.


Was not the correct fan, we all thought it was

Whenever you get the chance, please email me a photo of what your fan looks like so we can try and find the correct product.

I discovered the cap missing on my RV during a cross-country trip. After installing a temporary cover/cap, I stopped at various RV centers along my route to find a replacement with no luck. I went on-line to etrailer and found an exact replacement for my vent! We finished our trip and as soon as we got home I ordered 2 of the assemblies. Within a week, the vents arrived. Sure enough, an exact replacement! Now I have a spare for any future issues. Thanks for the great selection and service!


We had the item shipped to our destination without any problem. Thank you for that. The gentleman that works at the campgrounds put it on for us, which was really nice of him. So, thank you again for shipping to our destination and for being on time with it.


Great product! Exactly what I needed to solve my problem


Great service and quality products


Well made and fits exactly as the origi nal.


The replacement cap fit perfectly on my 2019 Reflection 337RLS. Order was delivered earlier than promised.


Great product at a great value on time


Great replacement for factory installed roof vent for Grand Design Reflection 303RLS. I could not find any dealers in BC Canada that carry the roof vent cover yet it is a crucial cover to protect from rain getting inside roof.


Exactly as advertised. Amazingly fast order fulfillment, arrived in incredible three days during holiday/supply chain fiascoes.


Easy to install and tough enough to handle the weather.


Great pricing on these vents at 1/2 off. Better quality than the originals on my RV. Only used the visible cap that had broken down under UV after 5 years- base was still in great shape. Caps fit perfectly.


The vent was a great surprise. The quality was unexpected for the price. I used it to vent my truck canopy and it works great. The low profile keeps it out of the way when loading my ladders. Good product and quality. I'll buy it again.


As described on web site.


Item was received promptly - securely packaged. Look forward to doing more business with


Great replacement for broken one.


We have ordered mushrooms from your company before. We just love them.


I've been using etrailer for years it's my go to part's store


Courtney B was great. She helped make sure I got what I needed and that it was delivered in a timely manner. I love ordering from etrailer.


Works like it’s supposed to


This was a perfect fit and easy install.


Exactly as described. Quick shipping

  • White Side Wall Vent For Enclosed Trailer With Refrigerator
    I do have an option for you but the Mushroom Vent - White part # 37202-29125 is designed to be a roof vent. I recommend to use 2-Piece Polypropylene Trailer Vent for 3" Diameter Hole - Black part # WHMAV2-WAVT2 which is designed to be installed on the side walls of your trailer and has a cover to prevent water from getting in. I have attached a very helpful video for your reference. You will need Zinc Sheet Metal Screw - 8 x 3/4" Indented Hex Washer Head part # 31071 to install it.

  • How Does The Mushroom Style Plumbing Vent Install and Work
    The Mushroom Vent # 37202-29125 you referenced is a replacement vent for the sewer and holding tanks. The mushroom vent mounts on the roof of your RV or camper to allow odors and gases to escape without entering the living quarters. The mushroom vent does not have a fan built in so no wiring or switches are needed. An option for a roof sewer vent that does have a fan is the Ultra-Fab Solar-Powered Plumbing Vent # UF53-945001. This upgrades your existing roof vent, or will add a roof vent...
