VEVOR Chimney Cap, 8" x 8" Flue Caps, 304 Stainless Steel Fireplace Chimney Cover, Adjustable Metal Spark Arrestor with Bolts Screws, Mesh Chimney Flue Cover for Outside Existing Clay Flue Tile

Be aware that this requires assembly - check the video, the instructions with the package are sparse. The 8x8 unit is pretty much exactly 8x8 - no margin - my 8" flue is about 8 1/8" so the unit was a little small. Unfortunately they don't appear to have a 9x9. Other than that, unit was very well packed and the quality seemed good.

The product came with the worst instructions I had ever read. The pieces were sharp and dangerous. Unless you wear cut proof gloves and sleeves I would suggest you do not even attempt putting it together. I had extra parts for some areas and missing parts for others.Again I must stress that it was dangerous to put this together and had limited instruction with no parts list.Also did not fit the chimney size advertised.

Not quite sure how the cap was supposed to attach to the chimney but made it work and has lessened the amount of rain that comes in now.

Easy to assemble and the perfect "top off" to the new chimney

Just what I expected
