What to Check First

Do Not Do This
Do not force round fittings onto it, treat it like rectangular TDC, or sling it where the flat sides can collapse.
Why This Matters
Distortion changes fit, airflow area, appearance, and connector performance.
Verify against: approved shop drawings, manufacturer instructions, project specifications, foreman direction.
