How do I square up my hanger points off a structural I-beam

Use the 3-4-5 rule to establish a right angle. Measure 3 feet along the I-beam edge, 4 feet out perpendicular from it, and adjust your angle until the diagonal distance between those two points measures exactly 5 feet.

Field checklist

Ask Foreman

Hey boss, I’m checking hangers & supports: How do I square up my hanger points off a structural I-beam? I found the likely issue and want to verify the next step before I lock it in. Do you want me to adjust it now or check the drawing/detail first?

Verify before acting

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.
