Keep the damper handle visible/reachable where required.
Seal the joint cleanly per project specs.
Avoid screw tips projecting into problem areas when avoidable.
Check that flex/round connection can land without stress.
Ask foreman
Do you want this spin-in damper handle facing the access side, and is this location approved before I cut the main?
Do not
Stop before cutting a main if the tap location, size, airflow direction, or damper access is not confirmed.
Why it matters
Finish work is where rough-in becomes visible, inspected, balanced, serviced, and turned over. Clean install and access matter.
