Magedori: Conduit Bending Calc
Offsets, Saddles & Kicked 90s
$1.00 · Designed for iPad. Not verified for macOS.
One test bend and the app learns your bender's real radius. Every mark after that matches the pipe. New in 1.2: kicked 90s, and EMT, IMC and Rigid in inches.
Stop hunting through preset lists for your bender.
Make one test bend and the app learns how your bender actually bends. From then on, the numbers match the pipe.
CALIBRATE TO YOUR OWN BENDER
Benders of the same size bend differently with make, age, wear and the hand on the handle. Book values drift. Bend a 90° on a scrap piece, measure it once, and the app works out your real centerline radius for that size and keeps it.
SEVEN BENDS
• 90° stubs and any-angle bends
• Kicked 90° (new in 1.2): marks for the 90° and the kick, distance between them, shrink along the run
• Offsets with distance between marks and shrink
• 3-point saddles
• 4-point saddles
• Single bends at any angle
• Parallel runs: how far to shift each mark
MARKS FROM THE PIPE END, IN ORDER
Results are a list of distances measured from the end of the pipe: ① bend start ② bend end ③ cut. Lay your tape along it and mark. Choose whether you measure to the back, the center or the inside, and the red line in the drawing moves to show you.
TOLD WHY IT WON'T BEND, AND WHAT WILL
If two arcs would overlap, the app says so, says by how much, and offers an angle that works. One tap switches to it.
EMT, IMC AND RIGID, IN INCHES
All ten trade sizes from 1/2" to 4" for EMT, IMC and RMC, with fractions to 1/16". Metric steel conduit (EN 61386) and Japanese JIS conduit are included too, in millimeters.
NEC RADIUS CHECK
Warns when the centerline radius falls below NEC Chapter 9 Table 2.
BUILT FOR THE JOB SITE
• No sliders. Type numbers on the keypad or tap +/- steps
• Every feature works underground or with no signal
• What you enter never leaves your device. To improve the app, only anonymous usage data (such as which screens are opened) is counted with Google Analytics (you can turn this off in Settings).
• No ads, no in-app purchases. One-time purchase, everything included
• Save calculations to history
Results are a guide. Final dimensions and code compliance are the responsibility of qualified personnel following local rules and your AHJ.
Requires iOS 17 or later. iPhone and iPad.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• The app now counts anonymous usage (such as which screens are opened) to help us improve it. Your measurements and history are never sent. You can turn this off in Settings.
• Shortened the bend radius label in the conduit & bender settings so it no longer gets cut off.
• Updated the list of our other apps.
