Keep Rectangular Duct From Tipping or Collapsing During Staging

Stage rectangular duct on stable bearing points and in a stack arrangement that will not tip, rack, crush lower sections, or damage reinforcement.

Stop if

• This wide transition is leaning on its flange and the stack shifts when we pull a piece. Where do you want it supported before we continue unloading?

Watch out

• Do not climb on duct stacks or lean oversized fittings where one bump can send them over.

Check

• Check the slab, dunnage, stack height, and weight distribution.
• Keep large or awkward fittings from leaning unsupported.
• Do not place concentrated loads on weak panels, access doors, dampers, or flange edges.
• Recheck stability after pieces are removed or the stack is rearranged.
