Hanger height against duct slope/offset not checked
Check hanger height against the offset layout before loading the duct. Offsets change elevation, travel, and support points.
Stop if
- Ask when hanger height, slope, offset travel, or support location does not match the drawing or field condition.
Watch out
- Do not hang the duct level through an offset that needs elevation change or clearance.
Check
- Verify duct elevation before and after the offset.
- Measure offset and available run.
- Use OWL to estimate travel/angle if needed.
- Set hangers so the offset is supported without forcing the duct.
Steps
- Verify duct elevation before and after the offset.
- Measure offset and available run.
- Use OWL to estimate travel/angle if needed.
- Set hangers so the offset is supported without forcing the duct.
Say this to your foreman
Can you verify the hanger heights before this offset gets loaded?
