This top cover come with a spin ring per your specified size. The spin ring itself is made to be over-sized. For example when you specify that you would like a 6" collar, the 6" spin ring would be 6-1/2" ID at the bottom of the spin ring and approx 6-7/8" ID at the top. This is designed to allow your liner to "slip through" the tile cap unrestricted. To hold the liner section "up" you can use our support clamp (eBay Listing #183489526683).
