The filters are 19 3/8 long
7" wide
3" top and bottom hole
The alternate replacement was C -7399/ discontinued
The closed I found are the C-3030 / C-3025
19 5/8 LONG
7" WIDE
3" TOP AND BOTTOM HOLE FOR $127
BUT THE CARTRIDGE IS 81 SQ INSTEAD OF 105 SQ
We still have the C-7399 in stock. Here is a link https://www.inyopools.com/Products/05100012069044.htm
Did you measure your existing cartridges and get 19-3/8"? We had another J-CQ420 owner and they thought their cartridges were 26-1/16" tall.
I saw that on another website but we can’t always trust that information. Have you measured your own cartridges?
You are correct I was wrong. I called the MFG and they informed me the measurements are 7" diameter, 3" inside and outside hole and the length 25 7/8. The 26 1/16 will work
That’s great. Thank you for coming back and giving us an update. Our PL0120 cartridges should work with the Jacuzzi J-CQ420 filter.
