Quality was excellent, delivery was good-Details of description lacking. Check your system before purchasing you will need a 4" male fitting and a 6" male fitting to be able to use this piece.

If I told you a flea could pull a plough, don ask me how, you just hitch up and go for a ride!

Nice thick material on this reducer collar. I had to modify/reduce an existing opening on my chimney chase cap this worked perfect for 4” double wall Duravent pipe to pass through. Left just enough clearance for a small bead of high temp sealant

The size is advertised as 12”-8” and IT IS NOT! Although they list the correct size (7.87”) in the specifications area, the main page does not list this! It will not fit on a 8” diameter stove pipe! BE CAREFUL! This is an example of very poor advertising on someone! Now I have to go through the process of returning it and finding the correct size reducer before the holiday!
