Chart
Conduit bending field mark layout diagram
Visualize hand bender marks, offset layout, and three- or four-point saddle bend sequencing.
Chart boundary
Does not replace the bender manual, bend-limit rules, raceway product data, or field measurement.

Bender mark and saddle sequence
The diagram shows where field marks belong; calculators still handle arithmetic.

| Method | Best fit | Watch point | Handoff |
|---|---|---|---|
| Stub-up | Single 90 degree bend with take-up | Bender take-up varies | Bender guide |
| Offset bend | Parallel shift around surface or obstruction | Shrink and spacing | Conduit bend calculator |
| Three-point saddle | Small obstruction centered under run | Middle bend orientation | Saddle multiplier table |
| Four-point saddle | Wider obstruction clearance | Total bend count and pull plan | Cable pulling review |
Notes
- Treat this chart as a planning and conversation aid only.
- Confirm current utility requirements, product markings, manufacturer instructions, and local authority requirements before field work.
- Use the linked calculator or table when the task needs project-specific arithmetic.
