In Spiral, Round & Oval Duct Install, I’m looking at: What do I do when not using proper lifting method for long spiral sections? What should I verify before I cut, drill, seal, cover, move, or install?

Do not

Do not try to muscle long spiral into place alone if it will bend or swing.

Why it matters

Project drawings/specs, shop standard, fitting orientation, sealing requirement, foreman direction, and approved round/spiral detail.
