Video Transcript for Ventline Ventadome Replacement Plastic Operator Knob Review

Today we're going to take a look at a replacement plastic operator knob from Ventline. Part number BVD0421-15. This is a replacement knob that you can use on your Ventadome vents or Northern Breeze RV vents. This is basically only a replacement. Nothing special to it. A couple little details. With this part number you get one knob.

However, it does not come with a little screw. It comes inside here. When you take off your old one, make sure you save that screw. Let's go ahead and try it on a vent we have here. Of course, it's a lot easier to do off the RV. This is a recently manufactured Ventadome.

I want to show you how to replace it. Pretty simple. Take a Phillips head screwdriver. Some older ones I remember using a flat blade screwdriver as well. Pretend this is broken and worn out.

Take your new one, line it up with the splines, push it in place, and reinstall your screw. Pretty simple stuff. An inexpensive part. It might be a good idea to have two or three on hand in case you break one when you're away from the store. Let's go ahead and try it out and make sure it works just fine. That'll finish it for part number BVD0421-15 from Ventline.

The replacement plastic operator knob.

The vent knob replaced the standard knob on my vent fans perfectly. I can now use the extending tool I also purchased to open the vent in the kitchen ceiling because the knobs fit into the tool perfectly.


Comments
The knob has worked perfectly, it fits the extending tool making the ceiling vent easily reachable without a stool or ladder. great system.

If you have a TAG nucamp camper don't get this product as it does fit the vent.

Received and installed new knobs on my RV windows. They are easier to use than the triangular knobs that came with the trailer. Its a shame that all trailers don't come with this type of knob on the windows. They are a quick easy install.


Comments
These knobs are easier in the hands for the older generation. They work great.

did the trick

It does the job as intended and I am glad for that. However, the plastic is very thin and we will see how long it lasts.

For my first time ordering from etrailer, I researched the on-line catalog, found what I needed and though it was a two dollar part, I ordered it snd received an order confirmation w/ tracking info. Several days later it arrived, was the right part and fit perfectly. What a world we live in! I won’t hesitate going to etrailer for my mext RV related purchase.

Fits perfect.

It fit the shaft. That's the main thing, but it came without a mounting screw. I would give it 5 stars if the screw were included. Fortunately I bought the steel handle as well, which did come with the correct mounting screw. It would be nice if this also came with a screw and it would have helped if there were a photo of the other side of this so you could see the size of the hole and the ridges that fit onto the shaft, or a diameter of that hole. It was a gamble (small one) but paid off. It fit, the screw from the other package fit, so now I have a working vent and a spare handle (the steel one). This does fit the standard Haulmark manual roof vent.

I broke my vent knob in the bathroom of my rv. This was an exact fit for my vent. Took 30 seconds to install, and worked as it should.

Perfect replacement part

I recently purchased an older houseboat with four broken knobs used to operate small awning-type venting windows. etrailer had the perfect solution for the replacement at an unbelievably low price and actual mailing cost. Even though the houseboat requires some specifically nautical parts, there is a relationship to RV parts. I am so pleased with my first purchase that I will first check with etrailer before making future purchases from the expensive boating supply stores.

I needed these Parts to replace a broken knob in my bathroom Vent. It was hard to find these Parts online. I called Northern Breese and Recommend I try etrailer.com to my surprise I Found them.

My vent cover and knob were shipped the same day! Easiest installation ever... took less under 5 minutes as I already had the ladder in place. The hinge just slid across right on the groove, bent both ends to secure w. needle nose pliers, went inside re-attached the arm, popped on the screen, then the new knob & I'm in business. (...I am over 60, and female... you can do this!) etrailer is now bookmarked as go to for parts!

Exactly what I needed. When the knob for one of my vents went "missing" I found this knob and the associated screw (V0423-01) at etrailer.com. It was delivered quickly and now I'm able to open my vent again.

worked like a charm, however I think the operator knob should be included with the Vent-line Ventadome

Ordered 2 of these to change the old knobs in my RV as part of changing things up inside. Knobs work well and alot better than the previous knobs.



- BVD0421-15

It's a knob! And it does what most knobs are supposed to do. I got tired of the metal angled crank cracking my skull every time I walked under it (I am a tall guy). Hopefully, I won't be ripping my scalp open with this one!



- BVD0421-15
by:

Works great! Be sure to align it just right, the parts aren't very forgiving.

Needed to replace a window handle with this type of handle. Even tho this is for a vent it matches the old handle, just needed a longer screw. Fast shipping and great price.
