    Kim D.
    from Maine asked:
    March 22, 2020
    Does this expand to fit tightly with the screw in the front to adjust? Is this fireproof? We have a hole where there must have been a stove previously, but we do not use that flue any longer and want to plug it up. Can this be removed easily?
    1 Answer
    While the screw may be adjusted to hold the plug in place, this product is made to simply seal a hole left in masonry after removal of a wood stove and its corresponding stovepipe. The plugged chimney could not then be used and would need to be repaired by a chimney sweep.

    I am looking to plug a hole in the back of my chimney that backs up to another room. Is this the right part to do that?

    1 Answer
    If you have a 6 inch hole that would be the correct part.

    Is it safe to pull the 8-inch pipe from a brick chimney and insert this plug in its place?

    WORKS AS ADVERTISED.
    Worked as advertised, fit perfectly in the chimney thimble. However, I do think that it is a bit overpriced based on the materials that went into its construction.

    Draft Stopper
    Seal chimney clean out tight. Wood stove draft is much better. Very satisfied quality and function.
