5.2.1 Bulk Storage Loose duct should be stacked parallel. To avoid exces- sive ovality on the bottom row, limit the stacking height to four feet for EB, five feet for DB duct, and 10 feet for RTRC. The bottom row ofduct should be laid on as level a surface as possible. Do not place supports under the duct, since this may cause exces- sive deflection and sagging.
