4 Inch Round Air Vent, HG Power Aluminium Alloy Louver Grille Cover, Soffit Vent with Built-in Screen Mesh for Bathroom Kitchen Office Ventilation, 3.74”, Black

Looks great installed. I used hot glue to hold them in. Handle with care, it’s light gauge aluminum.

I think there great , they are a permanent fixture.caulk and screw in place it’s over , done deal

Overall looks OK for the price point. Not entirely flat but soft enough that you can form it. The drawing says 3.74" diameter but it won't fit in a 3.75" hole, not even close. Plan to use a 4" hole saw.

For some makes no sense reason our RV manufacturer put a plastic vent in the floor right at your right foot in front of the toilet. Plastic and being stepped on didn’t last long. I searched a few years ago for even a plastic one that was round and had no luck. Then recently I ran across this one, exactly what I needed, aluminum and no vent adjustments sticking out of it. The RV manufacturer should have never put a vent where you walk, let alone plastic. This is much nicer quality than I was expecting and easy to paint what ever color you want it to be.

I needed to add ventilation to my RV and this is what I selected for the exhaust port. I'm very happy with it as the slotted cover seems very sturdy, which is necessary since I installed it on the floor of the storage compartment. Also the screen behind the slots seems sturdy. Finally the length of the flange behind is almost perfect for the depth of the (minimal) insulation in the floor of my RV.

Fits perfect looks great

Will greatly reduce airflow if used in a Exhaust Fan system. I feel like it would be OK for ventilating a very small area but not good with power exhaust or heating.

Love it. I did have a small issue, kind of my fault. I ended up pressing on the vent and it seems like it snapped inside although it went back to place and can’t notice at all. Still think it should be welded a little better. No biggie since it’s back in place and doesn’t move, you can't really tell and it’s not like something I will be moving or touching besides cleaning with a duster. Other than that it still feels good, just don’t do what I did an press on the inside. Still deserves 5 stars.

Ce que je voulais (Ok good)

As described

picture is totally misleading. It looks sturdy and suggests thicker metal used in fabrication. However, product arrived with the back portion buckled in a number of places and louvres are flimsily spot welded, also easily scratched. Expensive for such a poor quality product

No issue with the product itself but it was shipped in a bubble envelope and arrived bent in several places. Returned because of this.

Yup all good
