Starboard A Verified Purchase


December 3, 2021

I purchased this product to replace an air vent that broke on my certificated airplane. Was a bit tight but worked perfectly. My only negative comment would be that I now have one sitting around that I don’t need. Would be nice to be able to order these individually.

These vents fit perfectly, installed 4 of them! Used a 3.25 inch hole saw with a cordless drill so as to not drill too fast, drill from both sides then debur.

3rd order,using these in my utv . needed more air movement

Use this in my center console boat with a full windshield. Works great when it rains, but there is no air movement behind it. The windshield thickness was greater than the notch for the snapvent, so had to increase it with a dremel tool. Works very well and can close them when it rains. Well worth the price!
