This Item Is Used To Cap off the top of Masonry Chimney or Flue Tile Then Allowing The Liner To Pass Through The Collar. This Top Cover Uses Tension Screws For Attachment For Ease Of Installation. 

If you selected a 12" x 12" Top Cover, the base size for this cap would be approx 12 1/2'' X 12 1/2'' on the outside and approx 12 1/4" x 12-1/4" on the inside. 

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).
