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
That's great. Thank you for coming back and giving us an update. Our PL0120 cartridges should work with the Jacuzzi J-CQ420 filter.
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
I saw that on another website but we can't always trust that information. Have you measured your own cartridges?
We still have the C-7399 in stock. Here is a link http://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.
