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.

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. 266108

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. 528368

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. 373574

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. 365566

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! 44523

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. 178777

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. 525505

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

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! 70980

  • Replacement Manual Lift Knob on Dometic 1400 Powered Vent
  • The Dometic 1400 power vent is a Fan-Tastic Vent product. You will want the Replacement Lift Arm for Fan-Tastic Vent Roof Vents # FVK8011-05 if it is a mechanism issue. If it is just the knob, then you will use the Replacement Manual Lift Knob for Fan-Tastic Vent Roof Vent # FVK1142-09 or you can use the Replacement Plastic Operator Knob # BVD0421-15.

  • Dimensions of Ventline Replacement Plastic Operator Knob BVD0421-15
  • I went to our warehouse and pulled one of the Ventline Replacement Plastic Operator Knob # BVD0421-15 so I could measure it for you. For convenience I have prepared a photo with the key dimensions indicated. Overall depth, not shown in the photo, is 1-1/16-inch.

  • Replacement Operator Knob for Ventline V2094 Trailer Roof Vent
  • We offer a complete range of trailer vent replacement parts as well as entire vent assemblies. I linked our main page for vent replacement parts. For a replacement handle for a Ventline vent model V2094 you can use Replacement Plastic Operator Knob # BVD0421-15. If the inside splines of your knob are stripped then the new one should get you going again. If you do not have the original mounting screw that secures the knob then you can use part # V0423-01.

  • Ventline V2094 Replacement Knob and Operator
  • What you will need is the part # BVD0462-00 as this is the replacement operator for your V2094 roof vent and it comes with a new knob that will work with the operator. It sounds like you may have an older style operator that requires a knob that we don't carry anymore.

  • Replacement Vent Lid Cover and Crank Handle for Ventline Ventadome
  • It does look like you need vent lid # BVD0449-A01. For the knob only you would need # BVD0421-15. And for the whole arm assembly with knob use # BV0115-04.

  • Cannot Reach Knob On Ventline Ventadome Roof Vent
  • I recommend switching the manual vents out for the Ventline Ventadome Powered Lift Vents part # V2119-1-533. These vents can be opened and turned on/off with a switch powered by a 12V power source. The cut out is the same size as your existing vents so you can use the same opening to install the new fans. There is not a handle stick or extension to turn the knob open on Ventline Ventadome Roof Vents part # V2110SP-24 at this time. The Stromberg Carlson stool part # PA-202 is 15-1/2"...
