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.

Replaces the manual lift knob for your Fan-Tastic Vent clamp-on roof vent. Works with models 4000, 5000RBT, and 8000.


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.


It was an exact replacement for the handle that knob that broke. (The far, threaded end had twisted and snapped.) Although I've sold that trailer, the new knob worked fine for the few months that I had it.


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!


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!


Was as advertised. Installed easily on fantastic fan.


As usual the right product at the right price supported by outstanding people ...


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!

This works perfectly for me. You need to know that the shaft size is 1/2 inch and not 3/4 inch.


Customer support, Alex, was very helpful with helping me to determine if this item would work on my RV exhaust fan. Happy to say it was a perfect fit for my application.


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.

The knob fit our fan perfectly. Given that the star-shaped base that turns the interior knob had cracked and stripped, a version of this knob with some metal in those parts would likely make it a bit more durable, but it's working well now.


I would be happier to find this part made from a metal since it fits to a metal piece to work. Hence I’m having to replace it in such a short time.


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.


I got the right part the first time at a good price and it was delivered quickly. What more could a person ask for. Very pleased.


Description was spot-on—got the right replacement part on the first try.


Quick and easy!


Perfect replacement.


Fits perfectly - great to be able to get an exact replacement.


Excellent service!!


works like a charm

Works as expected. Fit perfect


The product was reasonably priced, exactly as shown and was received in just a few days. I thought the video was going to be unnecessary (after all, it's just a knob, right?) but in watching the video I knew that it was the right part and simple to install. Also, the shipping dept promptly notified me when it was sent out (only 1 day after the order). I have now fixed and closed the vent in my travel trailer and will DEFINATELY shop from ETRAILER.COM in the future.


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


Same as one replaced, plastic, which stripped and cracked. Wish one made of metal was available.


Always great service from your company. The how to install videos are great. Have helped me a lot.
