## Description

GROWNEER 4 Inch Roof Vent Galvanized Steel Roof Vent Cap, Removable Roof Exhaust Vent for Houses Bathroom Attic Kitchen(4 in-Bilateral) - desertcart.com

Review: Sturdy house vent - High quality metal and easy installation with no leaks.
Review: Not the best weather seal, easy to fix. - It seems to be built well. A little taller would be nice but I don't think there will be a problem. What I don't like is it is counting on the paint in the corner to keep water from getting into the house. It may take several years but I can see the paint cracking and water getting through the crack. Our solution is to put a small bead of RTV around the tube going through the base plate to seal it.

## Features
