This box of 3 identical pieces was sitting in storage for the past 5 or so years and is in like new condition... These galvanized metal Round Firestop Thimbles are adjustable in thickness from 3.5" to 7.5" and should work with 3.5" vent pipe... Absolutely no damage, blemishes, or corrosion that I can see anywhere on them! (please look at our rules and privacy policy) |
