A casket (burial) flag is a 5' x 9.5' cotton United States flag.
It is used on caskets of our service men and women if they either served at least one enlistment or if they served in any war. They must have had an honorable discharge.
When draping a flag on a closed casket, the "Union" rests at the head and over the left shoulder of the body of the deceased.
When a casket is displayed in the half-open position, the flag is folded in thirds with the outer fold displaying the "Union" next to the open portion of the casket on the deceased veteran's left.
When a casket is displayed fully open, the flag is folded into a triangle with only the stars and the "Union" showing. Then, it is placed in the center of the top portion of the casket lid just above the left shoulder of the deceased.
According to the United States Flag Code, the burial flag should never be allowed to touch the ground, nor is it to be lowered into the ground with the casket.
At the conclusion of the burial ceremony, the flag should be lifted waist-high by the pallbearers and held in this position for the playing of the "Taps". At the conclusion the flag should be folded in a triangle and presented to the deceased veteran's next of kin.
