The take-up in the chart belongs to somebody else's bender. BendRight lets you pick yours from the library or bend one stub and measure it, and then every mark it gives you is matched to the bender you're actually holding. Every screen takes your measurement first and puts the marks right under it in numbers you can read from the ladder: the distance between marks, whether it goes on the arrow or the star, and how much shrink to add. It works the bend on the bender's real radius, and it shows the chart number next to it so you can see the difference for yourself. Offsets, rolling and parallel offsets, 90 stubs, back-to-backs, 3-point and 4-point saddles, kick 90s, segment bends and concentric 90s are all in it. When the foreman sets the numbers, share them to the crew as a code, a QR or a link, and everyone's marks come out the same. There's a bending handbook under More with multipliers, deducts, gains, worked examples and field tips, and a Pull the Pin tab that opens the job lines IBEW inside locals post on their own sites, plus the IBEW Jobs Board. BendRight isn't affiliated with the IBEW, Klein, Ideal, Greenlee or Gardner; those names belong to their owners. Field tools under More work the voltage drop on a run, size the ground wire by the breaker and by the service, and show which phase and color a panel space lands on. They're a quick field reference; the code book and your inspector have the last word. No ads, no subscription, and the calculators need no signal; only Pull the Pin opens the web. You buy it once.
