Hon&Guan Soffit Vents 4 Inch, Round Exhaust Air Vent Cover with Built-in Fly Screen for Bathroom Kithchen Office Home, White

Nice product. Fit perfect. No tools needed.

Worked great! Even installed in colder temperatures and the plastic isn’t brittle

Worked like a charm. SImple to install and snapped in. The only adjustment was the insect screen was loose and had to get that in tight. Make sure you drill a 4.25" hole

I ordered the 4 inch vent to replace a broken outdoor vent that leads into my cellar. This is decently priced, looks clean, and does the job. I like that it has the 3 tabs that help hold it in place of the concrete opening. The rodent/bug grate is a separate piece and I'm not sure why. Maybe to allow if anyone anticipates putting cables through the opening slots? I've had utility companies do this in my last house. I used some gelled superglue to keep it from coming off as it pops off if pressure is applied from the outside, inwards.

Easy installation and helps draw cooler air in to help keep the back of my built in refrigerator cool. Nice strong plastic used.
