Sales-Floor Spiral Is Connected but Visually Crooked

Fast answer

Check the run from durable architectural and layout references, then correct measured centerline, elevation, hanger alignment, and fitting rotation. Exposed retail duct is finished work; mechanically connected is not the same as visually complete.

What to check

1. Check centerline and elevation with a laser or verified control points.
2. Look along the run for rod plumb, hanger alignment, seam orientation, branch rotation, and diffuser alignment.
3. Separate actual layout error from a dent, fitting distortion, or misleading sight line.
4. Correct supports and alignment before final sealing or finish touch-up.

Do not

Do not chase appearance by randomly raising one hanger at a time without checking the full run.

Ask the foreman

“The exposed spiral is connected, but the centerline walks across the sales floor. I checked the laser and found two hangers off the control line. Do you want those supports reset before finish cleanup?”

Why it matters

Customer-facing duct can fail the visual punch even when every joint is technically connected.
