This sweep kit worked well. The rods are sturdy but flexible. My only complaint is that one of the rod connectors wouldnot secure well, but with 30',I had two extra rods to use. I haven"t taken the time to see if I could make that one rodwork correctly. Also this style of brush fit easily through my damper letting me clean from bottom to top. Howeveryou will need to use a drill to make this type brush effective.
