Field checklist

Check shop drawing/fitting tag if available.
Look at cross-breaks, seam side, access doors, labels, and connection type.
Confirm airflow and next fitting.
Dry-fit/hold in place before final fastening.
Ask before flipping or modifying.

Ask foreman

This section may be rotated/upside down at [location]. Can you verify orientation before we lift and connect it?

Do not

Do not hang a questionable piece because “it probably works either way.”

Why it matters

A rotated section can move seams, access, slopes, labels, and fitting orientation into the wrong place.
