Air Vent 50001 2" Mill Mini Alum Louver, 6 PCS/CTN

It's a good product. Downgraded one star because of the way they insist on putting up '36 pcs/ctn' on the descriptor line which is very misleading. Each package comes with six pieces.

My husband and I built a little house for my birds (ducks and geese). However, it didn't take much for the house to start smelling like ammonia, which told me I needed more ventilation. I didn't have any windows on the north side of the house because I was afraid that north windows would allow the house to be too drafty. When I found these, I knew that they were just what I needed. I put spaced four of these as evenly as I could across the North side of the house, as close to being under the eaves as I could. I also put two on the south side. These have made a huge difference in the ventilation of my bird house without causing it to be drafty. I am thrilled with the difference these have made and am very happy with my purchase and with the price I paid for them!

Fair warning 36pcs is not 36 pieces you get 6 with this order. Not happy will not order for this company in the future...

We used these in the side of a homemade computer cabinet for air exchange. I painted them brown and glued them in place. They're light and work fine for what they were intended. They're mostly decorative to dress up the cabinet instead of having a bunch of holes in the cabinet.

What is listed as 36 pieces is actually six pieces. The company says that 36 pcs Is actually a measurement. Never heard of that measurement before. They did refund me my money and I got to keep the product. But still, I needed 36 and not six

I have bird-blocks but the internal mesh is so wide that yellow-jackets and other hornets started building nests. I hate hornets. With.A.Passion.I bought these louvers to keep them out of the vents and they work great. Of course the holes are not cut so precisely that they slip in with a perfect fit but I put a small bead of clear, paintable, silicon along the inside shoulder of the vent and they went in and stuck perfectly. I'd recommend these to anyone seeking a similar solution.

Will work good only if the holes have been drilled properly. Had to slit some of it to get it in the hole. Louver are soft. Can be easily cut with a sheetmetal shears.

It's claim that there are 36 is false. There are only 6.You pay twice for the six with them that you would pay at your local hardware store.Avoid this purchase. Buy local.
