Michael: Hi there, I'm Michael with etrailer.com. 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 etrailer.com.
Thanks for watching.
