This solid cast 316 Stainless Steel thru hull scupper has an internal flapper to keep water from back-flowing and a highly polished flange that makes your boat look great!  The long threads allow it to pass through thicker transoms and screw directly into a seacock.  The first 1/2" of threads are 1-1/2" NPT, tapered threads, so it will fit our plastic adapters.  316 stainless mounting nut included.
These are the original equipment fittings used on many offshore salt water fishing boats!
