Yeah Paul. I was just confused because the plastic guard is square and the Schluter valve seal is round.
I found this video addressed my problem /https://youtu.be/L4COYfBkEG0

Yeah Paul. I was just confused because the plastic guard is square and the Schluter valve seal is round.Didnt that valve come with a black plastic plaster ring. It is square in shape. the ring is used to set the depth of the valve and you put your board to the edge of the ring.
