approximately 1" off to the side of joist with spacing tabs pointing
downward.
Secure fasteners to board using board screws through hole B.
Repeat this process at every joist along remainder of board.

Place last deck board in desired location to be installed. Flip deck
board over being careful not to move the board side to side from
position. Place fasteners along Edge 2 (direction of install) of board
approximately 1" off to the side of the joist with spacing tabs pointing
