These are Groco's newly designed 304 Stainless Steel filter baskets for their raw water strainers.
As of Jan. 1st 2016 Groco's raw water strainers will ship with newly designed filter baskets. This change creates a much more streamlined series of replacement baskets with many fewer part numbers.
The new baskets have an improved handle design which you will be really happy with.
Sale of the old style baskets will cease as soon as supplies run out.
On the Fisheries website, every Groco strainer and every replacement strainer basket has been cross-referenced to make finding the correct basket for your strainer as easy as possible.
Please refer to the Specification Table in each product entry to see which baskets fits which strainers, or to find out which replacement baskets are compatible with each strainer.
