Hello, I was hoping you could help me identify the product in the picture below and in particular which replacement
basket it uses. It is in a 1995 hunter 40.5 and the basket measure about 1.75” in diameter and 5” tall.
It resembles your current product line and others have identified as a Groco as well.
Thank you in advance.

Hi Ed, it is best to figure out which ARG strainer that you have by checking it against the dimensions that I have here in this link:

Thank you.
ARG-755 is the closest match – A=6.5 B=4-5/8 with ¾” threads. I can’t get a good reading on the “C” dimension while it is installed.
So, I’m coming in about 0.1 over.
This would give me a BP-1, BS-1 or BM-1 basket, which seems a little larger in diameter than my current model. 1.9” spec vs 1-3/4” measured.
The height looks fine.
Sound right?
Thanks again

That should be correct since 1.9 is the smallest size that we go down to.
