Pool cap

I have a Wilbar 24’ round above ground pool part number I need is 12227 but mine has another part that screws to outside of it from the 6" side looks like a triangle but your replacement cap does not have the second part that screws on to the top cap.  Will your part still work 21341?

Hello Daniels - We have part number 16263 listed as the replacement for 12227. The triangular support for that top cap is part number 16262.
