A flat-oval 45-degree fitting was made on the wrong bend axis
Flat-oval fittings are handed by their bend axis. If the fitting is made the wrong way, do not force it; coordinate a remake or approved transition workaround.
Do not force or twist flat-oval duct to make a wrong-hand 45 fit the obstruction.
Check
Confirm easy-bend vs hard-bend orientation.
Check airflow arrow, seam position, and flange hand.
Compare the fitting to the actual obstruction path.
Look for whether a transition workaround preserves area and clearance.
Get approval before changing flat-oval geometry in the field.

Say this to your foreman
The flat-oval 45 at [location] is bent on the wrong axis for the obstruction. I checked the hand and airflow direction. Do you want a shop remake or an approved transition workaround?
