Prevent Round Duct From Rolling in the Laydown Area
Stabilize round and spiral duct so it cannot roll when straps are removed, material is shifted, or the floor is bumped or sloped.
Stop if
- This spiral stack is on a slight slope and we are about to cut the delivery band. What approved blocking or rack do you want before we release it?
Watch out
- Do not trust a round stack because it looks still, and do not use loose scraps that can kick out as the only restraint.
Check
- Choose a flat laydown area outside travel paths.
- Use the approved rack, cradle, dunnage, or chocking method for the material and site.
- Release delivery restraints only after the stack is stable.
- Restabilize the remaining pieces every time one is removed.
