Wall Cap Model Broan 843BL 6" (843BL)
Wall Cap Model Broan 843BL 6"
Black wall cap with damper
This wall cap is better then those I found in local big box stores. It is well made and should last for years. Mine seems to seal just fine. I'm using it with a Panasonic 240 ccm in line fan so there is no issue with the fan being able to open this cap. I would buy again
