Measure the duct opening, not the grille frame

Do we need the opening size or the outside grille frame size here?

I'm checking measure the duct opening, not the grille frame. I measured the field condition and want to verify the reference point before I act. Do we need the opening size or the outside grille frame size here?

Measurement question: Measure the duct opening, not the grille frame. I have the location, photo, and measured reference point ready. Who should verify before this becomes cut, ordered, drilled, or covered?

Watch out

Do not order or cut by the visible trim/frame size.

Check
