How should I handle a radius elbow that will not clear a beam?

Do not smash, flatten, or force the radius elbow into the beam. Verify the conflict location, measure the available space, then bring the foreman/detailer real options before changing the fitting shape.

['A radius elbow hitting steel is a coordination and airflow problem, not permission to freestyle the fitting. First prove the conflict: grid, elevation, duct size, elbow direction, and exactly where the beam steals the turning space.', 'Likely recovery paths include a revised elbow, offset, transition, split duct, shifted run, or an approved square-throat/square-heel elbow with a proper vane/detail if the design allows it. The key is that changing an elbow changes airflow and pressure, so the final call belongs to the foreman/detailer/approved documents.']

Stop if

• Use this as training guidance. The foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, and AHJ/code requirements always control the final answer.

Check

• A forced elbow can choke airflow, create turbulence, make TAB harder, and bury a coordination problem that should be fixed before cover.

Steps

• Confirm the latest drawing, detail, and revision for that run.
• Measure the beam location, duct size, available throat/heel space, and downstream equipment served.
• Check whether the conflict is structure, hanger elevation, wrong fitting, wrong layout, or missed coordination.
• Take a wide photo and a close photo with grid/elevation marked.
• Bring options instead of guessing: revised elbow, offset, transition, split duct, or approved vane detail.
