Video Transcript for Review of Fantastic Vent Fan-Tastic Vent Replacement Knob - FVK1140-09

Michael: Hi there, I'm Michael with Today, we're going to take a quick look at this replacement manual lift control knob for your Fan-Tastic Vent clamp-on roof vents. This is going to replace the lift arm for your clamp-on Fan-Tastic Vent roof vent. This is going to work for the model number 5000RBT.So if you do have a one of those Fan-Tastic Vent roof vents and you're needing a replacement lift arm, this is going to be the piece for you, because this is a Fan-Tastic piece. You can trust that it's going to work for your application. You're not going to have to worry about fit issues or compatibility or anything like that.

The screws going to go inside, it's going to tighten down, you can see the little star kind of bits around there that will allow it to fit into the groups on the inner cylinder there that will allow it to turn.But just in case you're still a little uneasy, give you a few measurements here. I'm going to call this for about two-inches in total width or wingspan there, and then our overall height we're looking at right about two-inches, maybe two and an eighth of an inch tall. The screw size the screw is going to come with, this is going to be a one-eighth inch diameter and one and three quarter-inch long screw, and so again, it'll just easily fit right in there. Make sure that this is going to secure nicely to your Fan-Tastic Vent roof vent.That's going to complete our look for today. Again, I'm Michael with

Thanks for watching.

@Jm We're glad to hear that!!


Your store was the only site I could find the handle for my roof vent , thanks for the quick service


Kimberly was outstanding solving my pro blem.


Work perfect


Exact part, fit like it should, and works like original.



Perfect! Exact replacement. I’m sure what caused it to break originally was operator errorand cheap pot metal, so I installed the new mechanism and marked it for directional open and closed.


Great replacement part!


The product was good and the customer service was great. I have purchased several items from etrailer and have never been disappointed.


I always purchase from e-trailer. Has what I need when I need it.



I installed the item, took it on a camping trip from Florida to Alaska. Has worked flawlessly.


Exactly what I needed and plenty of correspondence for tracking my delivery.
I will definitely use eTrailer again.

Thank you


Just what I needed!


This was direct replacement for the original handle and mounting bolt for the Fantastic Fan in our 5th wheel bathroom. It was easy to install, I did put a drop of Loctite on the bolt threads to prevent it from coming loose. After a year of use there hasn’t been any problems.


As advertised this was a perfect fit for the OEM handle that cracked and couldn’t be repaired. Once again thank you Etrailer for having the parts we need as usual and getting them delivered promptly!


It's nice to be able to find parts to fix something, rather than having to replace the whole assembly. Replacement knob perfect match for original.



Still works fine!


fast delivery, looks like what i needed thank you , makes it so the wife can reach vent without a step stool


Holding up better than the original one!


etrailer always has what I need to stay on the road and gets it to me in timely fashion. Hard to function if you can't open your fantastic fan!


Manuel lift control knob for Fan-Tastic vent fan was perfect fit. Looked at three different RV parts and sales centers during my last travels from Florida gulf to home in S. C. And no one had part listings in there systems. When settled back at home base I found found part within minutes few days later part arrived Installed it myself with no problems now my vent fan is Fan-Tastic again. No more bacon smoke in my RV truly a happy camper


This replacement part worked great, it's just unfortunate that it breaks so easily in the fantastic fan. The Max Air fan is simply a better choice to start with.

As I commented a year ago, The Max Air fan is simply a better choice to start with.


I ordered this handle for my Fantastic Fan that split open. I ordered two of them to have a spare handy if it should break again. was one of the few places that carried this specific handle and was appropriately priced.


Exactly the correct replacement pair.


7/17 ordered, 7/19 shipped, 8/3 arrived, it installed okay and works like new, all good. The only thing that stopped the "excellent review as the shipping time part. Part shipped from Wentzville, MO to Oceanside CA by USPS, and we all know USPS has major issues for the past twenty years and recently they have been completely unreliable. I am not sure why businesses still use them, obviously the USPS distracts from the otherwise good service quality this particular company has.


Fast and easy fits great


Replacement parts for the exhaust fans on our 14 year old motorhome arrived one day early and everything fitted perfectly. It took me less than ten minutes to replace all three motor covers and handles. What a perfect experience from website lookup to delivery to installation. We'll be back!!


Product came quickly and works perfectly.
is not my first time to order from etrailer each time it is the same. Always go to etrailer when looking for parts or replacements.


The replacement vent knob arrived in just a couple days, which was great since we were camping in hot FL. It was easy to change and the new one from etrailer worked perfect. The only issue was the shipping-USPS not UPS as stated by the sales person. It was held for us at the post office and easy to obtain with ID. Camp sites do not have mailboxes.
