Stainless Steel Boat Deck Ventilators
Boat Vents - 3-1/2"x3-1/2"x1" Clam
Have flush mount vents for my fuel tanks and had water get into the fuel. Very costly issue. This seems like a very easy preventive measure to never have that issue again. Waa worried they would look bad but they dont.
I couldn't find a larger scupper any place until I tripped on your business.
I'm a Happy Camper or Boating person. Good job
