Mastercraft and MB Sports thread adapter

  • Sale
  • Regular price $19.99

Allows our drain plug lights to be installed in SOME masterctaft  and MB Sports drains. Some mastercrafts already have 1/2" npt (normal) drains.  Some have other designs.  If you want to make sure, email us a photo of your drain plug on your particular mastercraft.  Typically you can tell if you need this adapter by looking at your drain flange.  If it has 4 screws on the garboard flange and your plug has a rubber O-ring on it, this is the adapter you need.
