Great
[This review was collected as part of a promotion.] A few days ago I received my NC-1 IN. GALVANIZED 18 X 18 6 PER, it arrived just in time I had to replace a base and this one fits perfectly well it was very easy to install I recommend them they are the best they are resistant and durable
very well made
[This review was collected as part of a promotion.] I picked this up for our bathroom vent pipe, i have used the Oatey's for the past like 30 years and never been let down, always well made and always a good water tight seal, which is important when it comes to anything on a roof, this one is very heavy made and takes a good hit to drive a nail thru it, i would recommend these to anyone needing a good dependable roof boot.
Great for leaks!
[This review was collected as part of a promotion.] We had an exhaust leak from the fan in our bathroom . I was able to get on top of my house, replace the old tube that was leaky and broken, with this new galvanized sheet of metal. It was easy to put in and it sealed the leak perfectly. I highly recommend it
