What do I do when reading duct size backwards or mixing width/height?

Confirm width and height orientation before ordering, cutting, or hanging. The right numbers in the wrong direction still create wrong duct.

Field checklist

Read the size exactly as shown.
Check plan, section, and fitting orientation.
Compare to opening/equipment/boot connection.
Mark width/height on the piece when needed.
Ask if the drawing convention is unclear.

Ask foreman

Is this size shown width by height, and which side is horizontal in this location?

Do not

Do not flip rectangular duct dimensions because it looks close in the field.

Why it matters

Width/height mistakes usually fit just enough to get installed wrong.
