Slotted Hull Strainer
ASC Strainer

Now Available in Aluminum!



Access to the thru-hull fitting and seacock beneath GROCO hull strainers is made easy with the patented access door design.

Now there is no need to remove the entire strainer to remove nuisance marine growth.

Aluminum models may be welded or screwed to aluminum hulls. Dimensions and ratios for aluminum models are identical to bronze models.
