Sprinkler main forces duct offset

Use O.W.L. as a quick field check for whether an offset has enough travel: Offset × Width ÷ Length is the field-memory idea, then verify against layout/shop detail.

Stop if

• The sprinkler main forces an offset here. Can we verify the offset travel/layout before I build around it?

Watch out

• Do not fabricate an offset off a memory formula without verifying the drawing/shop detail.

Check

• Measure the offset needed.
• Measure the available length/travel.
• Identify the duct width involved.
• Use O.W.L. only as a rough check, not approval.
• Ask foreman/shop detail before fabricating or changing route.
