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
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
Perfect fit
[This review was collected as part of a promotion.] The Oatey NC-1 galvanized 18 x 18 6 per roof flashing cover was exactly wwhat I needed to finish my bathroom remodel. Just like all other Oatey products this one is well made and does the job right.
