Using narrow strap that pinches flex

Use support that cradles flex without pinching it. Narrow straps can collapse the duct.

Stop if

• This strap is pinching the flex. Do you want a wider support/cradle here?

Watch out

• Do not cinch flex tight with narrow strap or wire.

Check

• Look at strap width/contact point.
• Replace narrow/pinching support with approved wide support/cradle.
• Keep flex round at the support.
• Add support spacing as needed.
• Recheck airflow path.

Steps
