BendPro: Conduit Bending Calc

Now FREE! Professional conduit bending calculations used by electricians worldwide. Supports 17+ bend types and 30+ bender models.

BendPro is the fastest, most accurate conduit bending calculator built for electricians, apprentices, and contractors working in the field. Completely FREE — no subscriptions, no paywalls.

PRECISION CALCULATIONS Every calculation uses the centerline radius algorithm, accounting for your specific bender model, shoe size, conduit type, and conduit diameter. The same math engine that powers the calculations also drives the visual bend diagrams — what you see is what you'll bend.

QUICKCHECK™ VALIDATION Color-coded instant feedback tells you if a bend is possible before you even lift the conduit: • Green — bend is feasible • Orange — bend may be difficult, double-check • Red — bend is impossible with current settings

SUPPORTED BENDS • Offset • Rolling Offset • Matching Bends Offset / Matching Centers Offset • Parallel Offset • 3-Point Saddle • 4-Point Saddle • 90° Bend • Kick • Kick with 90° • Matching Bend Kick / Matching Center Kick • Parallel Kick / Parallel Kick: Forward • Compound 90° (Circle, Rectangle, Square obstructions) • Segmented 90° • Multiple Bends on a single conduit
