In Equipment Connections: RTU, AHU, VAV, Fans & Louvers, I’m looking at: What do I do when duct connection to RTU curb does not line up? What should I verify before I cut, drill, seal, cover, move, or install?

Do not

Do not assume the curb is right just because it is installed, and do not field-adapt the opening without approval.

Why it matters

Project drawings/specs, equipment submittals, manufacturer instructions, access/service clearance requirements, foreman direction, startup needs, and approved equipment connection details.
