Liner loose after field cut

Field cuts can leave liner loose at the edge. Secure or repair liner before that edge becomes hidden inside the duct system.

Stop if

• The liner is loose after this field cut. What edge treatment or repair do you want before we connect it?

Watch out

• Do not connect over loose liner and hope airflow holds it down.

Check

• Inspect the liner edge after the cut.
• Look for peeling, torn facing, or gaps between liner and metal.
• Verify approved adhesive/pins/edge treatment.
• Ask before trimming or patching liner.
