Video Transcript for Review of Maxxair - RV Vents and Fans,Enclosed Trailer Parts - MA00A03550K

Today, we're going to take a quick look at the Replacement Key Wall Control for MaxxFan Plus and Deluxe. This is going to be a 4-key wall control for your MaxxAir fan. It's going to give you your Fan Off, On, your Vent Open, and Close controls so you can easily control your vent and fan from across the room. You don't have to get up and operate it every time. We'll also have little covers for our hardware here. We get two screws to get this mounted onto the wall.

On the back of that mount, you'll see our connection to power there. It's just going to be that little plugin, and then these two holes are going to be our mounting holes. So, whenever you have your screws in place, you'll actually have the little black portion behind it. The little connector in between is just for shipping, but, basically, that just connects into that little opening at the top so it provides a secure hold on your wall mount there.Again, we'll have all four of those controls so we can easily operate our MaxxAir fan from wherever we are. This is going to work for the MaxxFan Plus, Part numbers 4751KS or 4951KS, and the MaxxFan Deluxe, which is going to be 8751K or 8951K.

This is going to be about 3-1/8" long, about 2-3/8" wide, and about 1-1/8" deep.That's going to do it for our look at the Replacement Key Wall Control for MaxxFan Plus and Deluxe.

  • Will 14" x 14" Roof Vent Fit a 2015 Lance 1052 Camper with 14-1/4" x 14-1/4" Roof Opening
    You will definitely be able to install the MaxxAir MaxxFan Plus Roof Vent w/ 12V Fan # MA00-04751KSX on your 2015 Lance 1052 truck camper just fine. Basically anybody that measures 14" or 14-1/4" for a vent has the same vent dimensions. People will measure either the opening on the inside or outside, the lid, or even just the opening in their roof which is where the slight differences come into play. If you measured 14-1/4" then the MaxxAir vents will fit like a glove. Please note that...
