Saddle/band support where required not used

Confirm the round/spiral/oval fitting and connection before forcing or cutting: not using saddle/band support where required.

Set the support line before locking the run. Round duct should stay round, level/aligned, and supported without crush points.

Round, Spiral & Oval Duct 2nd Year YELLOW

Stop if

Ask when finish/exposed spiral, connection type, seal method, support, or fitting orientation is unclear.

Watch out

Do not let straps or hangers crush the spiral or pull it off line.

Check

Check centerline
Adjust hanger height
Support without flattening the duct

Steps

Verify size, fitting type, and airflow/branch direction.
Check the connection method: coupling, collar, flange, gasket, screws, or sealant.
Support the duct so weight is not deforming the joint.
Focus on the actual issue: not using saddle/band support where required.
Photograph or mark the condition if someone else needs to approve it.
