Stainless steel thru hulls and scuppers

If the plastic thru hulls or scuppers on your boat are showing signs of fatigue, you may want to replace them with better, long lasting stainless ones.
 
All of the stainless steel boat thru hulls and scuppers we carry are cast 316 stainless with highly polished flanges that look like jewelry!  Beware less expensive products that may be "mystery metal"... technically stainless, but very low grade.  You don't want to go to all of the time and expense of changing out your fittings only to have them rust.  These are the same thru hulls used by many better builders... especially builders of off-shore fishing boats that see lots of harsh salt water conditions.
