New Cast Aluminum Spout 7/16″.  This spout is compatible with both the aluminum bucket with flat cover and the sap sak holder.  Drill 7/16″ hole approximately 1 1/2-1 3/4″ deep into the tree at a slight upward angle.  The hole on the narrow end that goes on the tree is on the bottom, as it will be catching sap as it rises in the tree.

This spout will last a lifetime if taken care of.
