Flexible Connector at Equipment: Enough Slack, No Collapse
Install the approved flexible connector straight, sealed, supported, and loose enough to isolate movement without sagging into the airflow.
Stop if
- Is this flexible connector aligned and loose enough for isolation without sagging or carrying duct weight?
Watch out
- Do not stretch it drum-tight, leave it folded into the airstream, use it to correct a large misalignment, or let it support the duct.
Check
- Verify connector material and width
- Keep the connection aligned before fastening
- Provide even slack around the full perimeter
- Check for folds, twists, punctures, and contact with sharp edges
- Confirm adjacent duct is independently supported
