** One worker should tilt the pipe, and the other should remove the top cap and set it aside.
** One worker should tilt the pipe, and the other should remove the top cap and set it aside.
**While the one worker holds the pipe tilted, the other inserts the bar. Be careful not to knock the bundle against bars or pipes below the ceiling. Also, do not let the bar fall into the straightening unit. Set it carefully at the bottom of the pipe.
