Didnt have a 3-1/4 hole drill but i had a,3 inch. So i carefully exspanded the hole using a dremel tool . Installed into the lexan quite good. Simple solution for getting some air into my new designed door . I would recomend this product for lightsport aircraft

I purchased two pairs of these snap-vents for use on my Rally-cross GTI. I had replaced all my glass with lexan windows and needed a way to aid ventilation. After a brief google search I found these vents. Some have said that using the recommended 3.25 hole saw is not advisable as it makes the hole too big. This is not a fault of the hole saw size but excessive run out in your drill/or drill chuck. Use a good drill and go slowly and you get perfect results. I used an air drill.

Easy to install and use. I think they are a good buy for the price. Regarding the previous review, perhaps they work better in some applications than others, but I was satisfied with the results.

These vents were easy enough to install in my motorcycles windshield, and look like factory installed. Unfortunately, they didnt give me the airflow I was hoping for. I have a fairly long beard, and was trying to eliminate the Burble, which causes my beard to fly up into my face and field of view. Back to the drawing board I go. Thanks.

Q: Do the SnapVents close fully so air doesn't get in?

These snap into the opening where they will be installed. They have a vent on one side. If you rotate the vent towards the front of the aircraft, the air will flow in. If you twist it 180 degrees, the airflow will stop. It will not be airtight but the air will not be flowing in. You could use a seal to create an airtight closed position but we do not have any details on exactly how that is done.

Q: Is this type Snapvent ok to install in door windows?

This will depend on your application. Since this is an experimental part it is up to you to decide where you think this will best be placed. There are general installation instructions here under the documents tab that you can refer to. This vent has been used in plexiglass/lexan door windows in the past, but can be used in other areas of the aircraft.
