Items were as described and as received. There is a discrepacy with the mounting screws though.
They are tiny. The original in our motorhome are self tapping and quite a bit larger, which makes sense. The little screws in the shipment would not have made the garnishes secure. But otherwise, many thanks for quick service and shipping was pretty fast.

worked perfectly, arrived on time

Perfect. Needs to be trimmed, of course, but not all ceilings are the same depth

by: Dean 06/12/2025

This vent garnish ring(s) fit perfectly and is well manufactured. The item(s) comes with the mounting screws, although screws with larger shoulders were chosen and used in my particular case being my preference. Shipping was on time with no damages. “Thank you for your years of service and support.”

That is great, Dean! I am so glad that you have been able to find the right parts for your trailer :) When is the next trip?

The perfect thing to get that cracked, old FanTastic trim looking perfect and new! Trim to the correct length with a jigsaw and a coarse tooth blade. Perfect fit and perfect color match!

Perfect Fit.

Oh yay! So glad to hear that Clifford. :) Are you fixing up the RV for an upcoming trip?

by: Geoff 10/27/2020

Anyone who owns an RV knows how the vent garnishes crack at the corners. This replacement garnish will correct that.

I'm pleased with the replacement and the assistance I received in ordering the precise part for my 2008 RV. But I am even more pleased with the service I received when I, unfortunately, had to return the part due to damage during shipping. Following a quick and pleasant call with customer service, a new part was immediately sent to me in a reinforced shipping box. I appreciate the support.

by: Bill 11/30/2019

Needed a ceiling garnish for the power ceiling vent that had the wrong one installed and was cracked.
as always etrailer has the difficult hard to find items for my older RV. etrailer is the FIRST place I go to for parts. The NEW part fits like a glove and no need for modification to make it fit like the old one I took off, it even came with the mounting screws WOW
Thanks etrailer

Two corners of the ceiling vent fan garnish in the bathroom of our 2014 Tiffin Allegro RED 33AA had cracked. Searched on line and found a replacement at etrailer.com. The replacement was shipped promptly and fit perfectly. Pleased with the quality and service.

by: Nick 04/26/2025

Great company, fast shipping and perfect fit. Thanks for having the right specialty parts.

by: Roy S. 04/05/2018

Not too much can be written about a RV vent garnish moulding. Most brands are made from thin plastic and are fragile. Care must be taken not to over tigthen mounting screws when installing or the lip will crack. I received very good service from E-Trailer rep. Susan H. She helped me deterime replacement size and was very helpful. Roy S.

This is exactly what I ordered and fitting perfectly.
Thank you for your help order. Arrived in a few days.

by: David 02/11/2021 One Year Later

I had to do some adjustments by cutting an 1/2" or so in order for it to fit perfectly into the AC space. I was hoping for a more sturdy product. But, it did the job.

I find the product to hold up to standards. However, the motor is a bit noisy. I purchased the same product from a different distributor and there is quite a difference on the noise factor, quieter. Perhaps, it was the manufacturer.

by: Debra 02/06/2019

Hey!! I love etrailer!! Trim pieces came package so well with no damage. Our camper is an older one. Finding replacement things are tricky to find. But they worked beautifully with a little work!! Thank you so much!

Availability Of 2" Tall Garnish For Dometic Vent Fan
Hello Andrew, thanks for reaching out. We do have a 2-1/8" garnish for a Ventline roof vent part # VA0445-26. That would be our closest option to what you are looking for. Our smallest Dometic garnish is 4-1/2" tall part # FVK2040-80. I have heard of people taking these and cutting them down to size so that might be an option. If you do that just cut carefully because they are prone to cracking. A nice sharp fine-tooth hack saw should do the trick.

Hey James! The Garnish for Dometic FanTastic Roof Vent # FVK2040-80 is exactly what you're looking for!

This technically has "rounded" corners, but they are more square than the other options available.
