This flange matched the size I needed to match the flange base on my Westinghouse generator. It allowed me to use an extension exhaust for my generator box. This enabled me to use the generator which has a CO detector built in without interuptions. The flange made a very tight seal and no CO was detected in the box.

I paired it with a Walker 1-1/4 Inch Steel Exhaust Flex Pipe # 40001 which fits perfectly.
