BendSource: Conduit Bending

Calculate EMT offsets, saddles, and 90° marks with source-linked formulas, fraction input, and bender values you can verify.

BendSource turns supported EMT layouts into tape-ready fractional marks while keeping the formula, bender value, rounding rule, and source visible.

CALCULATE SUPPORTED EMT BENDS

• Offset bends with spacing and shrink • 90° stub-ups and back-to-back 90s • 3-point saddles using sourced 45° and 60° center-angle methods

TAPE-READY MARK SHEETS

See numbered M1–Mn positions, bend references, spacing, and rounded inch fractions in one place. Choose the rounding increment used for the displayed marks.

CHECK THE METHOD

Open Formula Mode to review the substituted values, unrounded result, preset provenance, manufacturer document, cited pages, and applicability notes.

USE YOUR BENDER VALUE

For supported 90° methods, you can save a take-up value read from your own bender or manual. User-entered values remain clearly labeled Check Bender and are never presented as manufacturer presets.

PRIVATE AND OFFLINE

Core calculations, saved Mark Sheets, and user presets stay on your device. BendSource has no account, ads, analytics SDK, or subscription.

SCOPE

Version 1 supports 1/2-inch, 3/4-inch, and 1-inch EMT for the bend methods shown in the app. A calculated result confirms the math and selected inputs; it does not claim a physical bend, jobsite conditions, or a specific bender has been field verified.

Offset calculations and the source catalog are free. One Lifetime Unlock enables the other supported calculators, saved Mark Sheets, and user presets.
