Measure a Field Transition From Actual Connection Faces

Measure the real inlet and outlet faces, offsets, elevations, rotation, and available length before laying out a transition.

Stop if

• I measured [inlet], [outlet], [length], and [offsets]. Can you verify which faces are fixed before I send or cut this transition?

Watch out

• Do not measure from insulation, curb edges, or rough equipment dimensions when the actual connection face is available.

Check

• Verify both connection sizes and flange types
• Measure face-to-face length
• Record horizontal and vertical offset separately
• Check rotation and airflow direction
• Confirm access and whether either end can move

Steps
