Conduit bending guides
21 guides, written the way the work is done: the marks, the order, the check, and what goes wrong. New to it? Start here — six short lessons. Need a number? The calculators do the arithmetic.
Learn to bend
- Bending, from zero Six short lessons for a first-week apprentice, each with a drill.
- How to bend conduit The guide, in the order you learn the bends, as procedures.
- How to use a hand bender Hook, arrow, star, foot pressure: a hand bender step by step.

- How to bend a 90 A stub-up from mark to plumb, and the checks that save a stick.
- How to bend an offset Two equal bends, marks the right way round, no dog leg.
- How to bend a saddle The three-point saddle over a pipe: notch, outers, and the shrink.

Fix it and check it
Pipe, tools and your bender
- EMT, rigid, IMC and PVC What bends differently, and what stays the same, from one pipe to the next.
- How to bend PVC conduit Heat, form, cool: hot box or blanket, plugs, and holding the shape.
- Measure your bender Take-up, gain, notch and springback from four test bends — your table, not a chart.
- Your bender card Your own take-up, gain, notch and springback printed as a pocket card per pipe size, stub marks worked out.
Reference
- 3-point vs 4-point saddle Which saddle for which obstruction, and how the marks differ.

- Conduit bending formulas Every formula on the site, from one triangle.
- Tape measure fractions Decimals to sixteenths, and a drill that keeps going.
- Conduit bending glossary Shrink, gain, take-up and the rest defined.
