18" x 18" Aluminum Gable Vent with Screen - Stylish Louvered Vents for Effective Attic and Shed Ventilation - Essential Home Improvement, Vent Opening: 16" x 16"

Work as they should had no problems so far

Dimensions as described and build quality is good for an aluminum vent. There are no screw holes in the frame; this is supposed to be mounted with adhesive. Still, there's plenty of room on the flanges to drive screws if you need to.The screen is pretty sturdy and fine enough mesh to keep most bugs out. Overall, a decent product.

Great product. Looks great, well made. Easy to install.

Works as expected, hasn’t faded in sun. Installation in a shed was easy.

Vent was used for my chicken coop and was sturdy and good quality.Was easy to install. I would by again.Took me about 30 minutes to install which included cutting opening.

I built a 4x8 shed a few years ago and last year I went in there and couldn't believe how musty it was there. I put one of these on either side of shed and if the wind is blowing even a little bit, you can put your hand by the downwind side and feel the air coming out. I just caulked around them to make sure the little critters and stinging things didn't have a place to get in at

Works as it should

Had the exterior of my 30+ yr old shed rebuilt after lots of wood rot. Decided not to reinstall the old glass louvre windows so ordered these vents. They were just installed and look great against the black shed. It doesn't come with screws so the hole was cut tight and vents are secured by silicone on the inside and outside. Looks great and will allow airflow. (Kept the old louvre windows, just in case I decide to use them in the future)
