This is our sd3 concave it is our stock concave all orders will be made with the sd3 unless a customer specifies a different concave. Any other concave than the sd3 will require a minimum order of
100 decks. We have over 12 different concaves but if each order had a different concave then we would go at a snail's pace. With this concave we can make the following sizes. 7.5 7.6 7.75 7.8 8.0 8.25 8.5 8.75 9.0 9.25 wide and pool decks
