    Rated 1 out of 5 by from I would recommend but the instructions need more info. The vent comes with a bird screen which needs to be removed if used as a dryer vent. It will get blocked with lint in less then 2 months if not removed. Your instructions say nothing which leads me to believe it is not approved as a dryer vent. Either come out and say this vent is not for dryer use or state that the bird screen must be removed if used as a dryer vent.

    Rated 5 out of 5 by from As a remodeling contractor we use these all the time to fix peoples exhaust fans which have previously been dumping into the attic causing, mold , insulation damage, wood rot, etc. Its an inexpensive fix that works great.

    Rated 5 out of 5 by from Just Right Could not find what I needed in local stores. I should have started with your web site. It was just right. Right application and works like it should. Plus it looks great on my roof.

    Rated 4 out of 5 by from Easy to install, works I installed this cap on the duct from a new exhaust fan in the master bath. The instructions were clear and easy to follow. There are no leaks in the roof and the vent works. I am happy. I plan to use the larger version of this on the new kitchen exhaust.

  • Rain/sleet noise

    Our contractor installed a 636 roof cap on our roof with about 4 feet of rigid ductwork going down vertically to the bathroom exhaust fan. Any time it rains or sleets, it sounds like we have a tin roof on our bathroom because of the rain/sleet hitting the roof cap. Do you have a suggestion for how to quiet the noise? Do you make any sort of hood that could go over the cap? Do you know if anyone else makes such a product? Thanks!
    Asked by: Dave
    Include at least one or two bends in the duct work to soften the noise. The direct vertical alignment of the duct is the cause of your noise problem.

    can this unit be used on a clothes dryer?

    Thank you for your question on the model 636 roof cap. We do not recommend using any of our wall or roof caps as a dryer vent cap.
