Protect Dampers, Sensors, Liner, and Internal Parts During Installation

This section has a damper and sensor upstream of the joint. I marked their locations-are these fastener and clamp zones clear before we close it?

Watch out

Do not assume the duct is empty, drive long screws blindly, or place clamps and temporary supports where they can crush liner or bind a blade or linkage.

Check

current shop drawing or spool
photo of the fitting, supports, and access
verified install path and final position
known internal components or finish requirements
what has already been checked
