I've had no issues with flatness, they are sufficiently flat for this application . There are some variations in the dimensions from piece to piece. Its not usually a problem, but it can add up on stacked pieces. The biggest variance has been the width of the slots, so I guess thats not a critical dimension for them.amazing! have you had any issues with the 8020 extrusion and resulting flatness?
