Raw Edge, Slip, Collar, or Flange: Connector Ends Do Not Match
Stop and identify what connector each end was supposed to receive. Two correct duct sizes do not make a usable joint when the end treatments are incompatible.
These pieces are the correct size and marks, but one end is flanged and the adjoining end is raw. I checked the spool and do not see an adapter-was a connector piece missed?
Watch out
Do not improvise a connector by cutting off reinforcement, flattening a flange, or filling the mismatch with sealant.
Check
Confirm the piece marks and current shop drawing.
Identify each actual end: raw, hemmed, slip, drive, flange, collar, beaded, or manufacturer connector.
Check whether a separate adapter or companion piece is missing.
Document both ends and hold the repair or remake decision for the foreman or shop.
