Stop if

Hold point on hanger rod sizing for duct weight: I have the location, photo, drawing/detail, and what was checked. Who should verify before this gets cut, covered, lifted, sealed, energized, or signed off?

Watch out

Don't guess rod size. Don't use wire instead of rod. Don't overload rod.
