Room to get tools on flange bolts not left

Bring the flange together evenly: not leaving room to get tools on flange bolts. Start hardware in a balanced way and do not twist the flange or crush the gasket.

Think about tool access before the duct is trapped. A flange joint you cannot reach is a coordination problem.

Stop if

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

Watch out

Do not install flanged duct where no one can tighten or inspect the joint without approval.

Check

Check beam/structure clearance
Confirm assembly sequence before final placement

Steps

Align the duct sections square.
Check flange faces, corners, gasket, and cleats/bolts.
Fix damage or missing parts before tightening.

Focus on the actual issue: not leaving room to get tools on flange bolts.
