Good, but I think that you need to write something in the web site to tell customers that the poly riser is not included in the square riser adapter ring. The picture makes it look like it is included.

the polylok square riser adapter ring did the trick for sure. Although I had never put a riser in, they were easy to work with and sealed real well. Had to use a Ramset to secure it since I hit rebar, but it set well.
