Questions & Answers

Will this roof cap work with WhisperCeiling 190 CFM Ceiling Surface Mount Bathroom Exhaust Fan, ENERGY STAR; Model #FV-20VQ3

Asked by: Gregg
I don't know--but check the output duct on the fan. If it 6" in diameter, use this roof cap. If it is 4' in diameter, use a smaller one.

Will this work to cap a roof top dryer vent?

Asked by: SquirrelsontheRoof
I wouldn't use it for a dryer vent, it is way to big. you need to get the smaller one model #636, it is for 3" to 4" vent hoses, Your dryer should be a 4" hose.

If I buy this product, do I still need a Back draft prevention Damper? Also what material is your bird screen? Is the screen metal? Thank you
Asked by: homeowner
You will not need an additional damper. This has one built in. The screen is metal.
