Stop if

Ask when connector type, gasket, cleat/bolt schedule, pressure class, or manufacturer detail is unclear.

Watch out

Do not guess the order on a manufacturer-specific connector.

Check

Check submittal/shop standard
Verify sequence before final assembly

Steps

Align the duct sections square.
Check flange faces, corners, gasket, and cleats/bolts.
Fix damage or missing parts before tightening.
Tighten or cleat evenly per project/manufacturer detail.
