Continuous Thread (One Start, One End)

Pourout design has a lip near the opening
to allow for more careful pouring.

Note: The thread spiral on -439 starts HIGH on the neck as compared to the -430 finish.

Remember it this way, higher number (  -439) starts high and lower number (  -430) starts low.
