4 in. Fresh Air Vent is rated 4.6 out of 5 by 9.
Rated 5 out of 5 by from Metal vent cover This vent was just what i needed. This house has a fireplace blower built in and the air vent cover is on the brick chimney. I was replacing a plastic one that had disintegrated. I wanted a grate inside to prevent birds and mice from entering but since it is for intake I didn't want the closing baffle. Also, there us a 90 degree curve in the pipe do I wanted a vent cover I could trim down easily to fit, if needed. With metal snips, thus cover was perfect to adjust to the existing installation. Works great!

Rated 5 out of 5 by from High quality fresh air vent I bought this heavy gauge metal fresh air vent to replace a plastic head vent on my daughters fireplace which had broken due to hail. All I could find in the store were the cheap plastic head models. I ordered this on the HD Web site and was very impressed with the quality. It was only $4 more than the cheap plastic model. Installation was a breeze.

My dryer ran literally two loads before needing to be disconnected and the screen emptied or else the clothes were still wet after an entire cycle. Ridiculous design!
