What do I do when not allowing for connector length in run measurement?
Measuring, Field Verification & Layout MarksFoundation layout starter — field verify before cutting/loading
Account for connector length before calling a run dimension done.
Field checklist
- Identify connector type: S-drive, TDC/Ductmate, slip, flex connector, collar, sleeve, transition.
- Check takeoff/fitting length.
- Confirm insertion/overlap allowance.
- Measure the full installed path.
- Ask before cutting if connector length is unclear.
Ask foreman
What connector/takeoff length should I allow for this run?
Do not
Do not cut straight duct to the opening-to-opening distance without connector/fitting allowance.
Why it matters
A run can be dimensionally correct and still short if the connection method was ignored.
