Confirm support type, substrate, elevation, insulation allowance, and conflicts
Support duct before stressing joints
Document conflicts before cover
Ask foreman
In Hanger Systems, Rods, Straps, Trapeze & Anchors, I’m looking at: What do I do when not verifying support requirements for externally insulated duct? What should I verify before I cut, drill, seal, cover, move, or install?
Do not
Do not hang permanent duct from temporary wire, unapproved anchors, another trade’s support, or sharp contact points.
