Groco's Access Door Slotted Strainer provides easy maintenance and emergency thru-hull access!
Access to the thru-hull fitting beneath this Groco hull strainer is made easy due to the patented access door design. There is no need to remove the entire strainer to remove nuisance marine growth. Aluminum models may be welded or screwed to aluminum hulls.

  • Door held shut by a ring and clevis pin
  • Ratio shown is size of strainer area compared to thru-hull pipe cross-sectional area
  • Smaller thru-hulls will have higher ratios
Also available with a perforated mesh cover for even finer straining (see separate entry for Groco APHS models)
