ABSTRACT:
A dog for latching a watertight door in the bulkhead of a ship, has a lubricant passage with a plug useful for forcing a grease pellet into the passage. The plug extends beyond the end of the spindle for the user to clamp a wrench for removing the plug from the spindle. The dog has two nuts mounted on the end of the spindle. One nut is a conventional nut for fastening the spindle to the bulkhead. The second nut is a cap nut for at least partially enclosing the threaded plug.
