Straighten, trim, deburr, or replace the damaged piece
Test fit before driving

In Rectangular Duct Assembly: S-and-Drive, I’m looking at: What do I do when snips are mangling the connector? What should I verify before I cut, drill, seal, cover, move, or install?
Do not
Do not force damaged connector metal and then hide it with sealant.
