Vent Systems 8" Inch White Circular Plastic Vent Cover - Louvered Air Duct Grill with Built-in Mesh Screen - HVAC Ventilation Grille for Bathroom, Soffit, Home, Shed, Garage - Indoor & Outdoor Use

I needed to install vents in my backyard shed and this 5-pack fit the bill. They are simple, with fit louvers and an insect screen on the back, and well made. I did not realize that they had plastic plugs to cover the mounting screws, a nice touch. Screws not included as advertised but not a problem. I was going to buy stainless steel screws but with the cover plugs, ordinary common galvanized - which I had on hand - are fine.Followup: I was concerned about UV resistance and decided to paint them. Found a can of plastic-suitable spray paint that virtually matched the color, cut a mask out of chip board and sprayed them in place. Looks great!

These look more like a bronze in the pictures, but I took my chances. They are actually a chocolate brown and matched our soffits perfectly. Super easy to install and work just as they should. I bought way more than I needed, and the return of my excess was very easy.

Perfect for to cover the old 1960’s vent cover we replaced. Air flow is good. Love the screen protection inside . Ordered another set for a neighbor

Used to dampen flow in low volume patio fountain.

Does not have sleve to adapt to duct

I used the vent covers to add soffit attic ventilation for my cabin.

This is merely a thin peice of plastic. No way to attach to 4 inch exhaust line

Super easy to install and worked perfectly

I like the scrwes caps they look and feel good qualityIll be ordering more for the next project
