Sturdy as shrek!
We switched from the vinyl to the broan 636 and have not looked back. No call backs for stuck flappers or leaks from wind driven rain.
Thank you for your 5-star review on the model 636 roof cap! We are happy this cap is working well for your application.
Great Vent in Multiple Sizes
Great Product. Easy to install. Also comes in a kit form with duct and accessories. Wish they'd supply tape instead of zip ties, but great product none-the-less.
Thank you for your 5-star review on the 636 roof cap! We are happy to learn this product has worked well for your application!
What else do I need to hook up?
Was having a new roof put on so I bought two of these to have the roofer install them while they installed the shingles. I thought this was a complete kit, but it does not have the tubing and connections to connect with bathroom fans. What additional parts do I need to purchase to make the connections? I do not see any metal tubing etc.
Thank you for your review of model 636. Please reach out to our Technical Team directly at 800-637-1453 with your application specifications. They will be happy to assist you further.
