RV Designer H810 Beige 4" Rotaire Register

Replaced the heat vent in our 2022 Grand Design Imagine with this so we could limit the heat somewhat. Worked great.

Perfect replacement size, but damper not fully attached to vent housing.

Good value. Solid fit. Works as advertised.

While this does have the ability to close, it has a ring around the edge that still allows air to get thru.It is well made, and will last a long time, however if you are looking for full closure and not partial closure, this product is not for you.

I was worried about the inner diameter of these as the description states 4 inches. My 2008 Lance 971 camper vent measured out at 3.75 inches. Everything looked the same on this new version so I took a chance. As you can see in the images, the diameters are perfect. The length is longer but no issues fitting behind our cabinets. Keep this in mind in your own install. Screw holes matched exactly and didn't require any new drilling. The flow only closes to maybe 80% blockage so I chose to buy a second to pass more air to our cabover bedroom area. Colors match exactly. Note the tolerance on the new vent is tighter than the previous and fits flusher against the cabinet. The look is neater but is noticeable side by side with the original. This also makes twisting the vent cap more difficult, but is still possible with care. Happy purchase.

Smoothly operates with my heating system in my RV.

We have a 2017 Imagine travel trailer. This vent is too tall for our ductwork; it blocks the airflow to the other vents when installed.

This was a easy install, however instructions were M.I.A. Took a few minutes to figure out how to take apart so it can be secured.

Arrived fast and works perfectly for my RV

Quite disappointed by how little the dampers do to stem air flow. I solved it by taping (using double sided tape) small pieces of leftover reflectix to the inside of the dampers (so they seal off the pipe when closed). That was easier than returning it.
