Hon&Guan 10.5"w X 10.5"h Gable Vents, Aluminum Alloy Wall Vents Attic Vents for Houses Door Vents for Exterior Doors [Outer Dimensions: 12”x 12”h].

I installed 2 of these vents on the north side of the house to cool my attic which has no real ventalation. On the south side I am installing a louvered 16 inch fan to draw out the hot air. The vents were to allow the fan to draw out of the attic so it wouldn't draw from inside the house. It was difficult to be near the vents due to the heat coming out. I haven't installed the fan yet but these have dropped the temp 20 degrees. And they look nice. They do not come with screws so I bought #8 stainless screws. You will have to open the mount holes a little to accomodate the #8 size. UPDATE== I HAVE THE FAN INSTALLED AND THE ATTIC IS AT 105 DEGREES WHILE THE OUTSIDE TEMPERATURE IS 100.

Nice and fast shipping

Bought a house that has no vents for the attic. Screen material is the right size to prevent pests while allowing air flow, the frame is nice and stiff, the vents are angled just right to allow air flow but not let rain in. Better than anything I can find at a hardware store. Does not come with any hardware, screw holes are counter sunk to give you flush head screw for easy painting.

Easy to install.

Had to return because I only measured my square opening (and knew this would fit). Turns out my diagonal was a bit smaller than this item, so I needed to return.
