Measure from a fixed end or obstruction.

Bender markarrow / star / notch

Tool manual defines the mark.

Mark spacingoffset or saddle multiplier

Calculator/table owns the arithmetic.

Shrink directiontoward obstruction

Transfer marks consistently before bending.

Decision reference

Show the field layout relationship among bender marks, offsets, shrink, and saddle sequencing.

Reference basis: Klein conduit bender guide, Greenlee bending manuals, and field conduit bending references.

Use notes

  • Use 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.
