In Hanger Systems, Rods, Straps, Trapeze & Anchors, I’m looking at: What do I do when support installed after duct joint is already stressed? What should I verify before I cut, drill, seal, cover, move, or install?

Do not

Do not loosen a stressed joint without supporting the duct.

Why it matters

Project drawings/specs, approved hanger/support detail, substrate/anchor requirements, foreman direction, and structural/coordination constraints.
