About Conduit Kit: Bend, Fill, Box
Know the length of the piece before you cut it. Pick the conduit and the kind of bend, type the dimensions — you get the marks measured from the end of the pipe and the cut length. Lay a tape on it and mark. ■ If it cannot be made, you hear it first The app finds the dimensions where the arcs would overlap (at 45°, an offset smaller than 2.688 in) before you bend, and switches you to an angle that works in one tap. ■ Kinds of bend 90° stub, custom angle, offset, 3-point saddle, 4-point saddle and parallel runs. Marks can be measured to the start of the bend, the center of the arc, or the theoretical corner. ■ Bend radius against the code Inside radius is shown with its source (NEC Chapter 9, Table 2 / Articles 342.24, 344.24, 358.24). The app does not reproduce tables — it cites them. ■ Not limited to a lookup table Fill is computed from the conduit ID and the conductor OD, so any size works, listed or not. NEC Chapter 9, Table 1. ■ Match the app to your bender Bend one 90° and measure the stub-up. That gives the real centerline radius of your tool, and every cut length after that matches what you actually make. ■ Keep it per job, hand it over on paper Add bends and sizing to a job and the take-off sheet builds itself. Sticks are counted by packing the longest pieces first, so the count is never short the way total ÷ stick length would be. Export it as a PDF. ■ Works with no connection Everything is computed on the device. Job records stay on this device only — they are not stored in iCloud, so they cannot move to a new phone. ■ About pricing The 90° stub (cut length and the radius check) and conduit size selection are free, always. Offsets, saddles, custom angles, parallel runs, pull box sizing, bender calibration, job records and the take-off PDF are a one-time purchase. There is no subscription. ■ Units and standards Switch between inch (NEC, North America) and mm (JIS, Japan). Conductor sizing is not offered in North America, because ampacity is given as a table (NEC Table 310.16) and showing only the voltage-drop half would give an answer that is too small. What the app shows is a guide for installation. Compliance and the final call belong to the job's own standards and a licensed electrician.
