## What is BendBox?

BendBox puts the math electricians use every day into one fast app that works offline. Get exact bend marks, size conduit, check voltage drop and count box fill in seconds.

CONDUIT BENDING
- Offsets, rolling offsets and parallel offsets
- 3-point and 4-point saddles, kicks, 90° stubs, back-to-back 90s and segmented 90s
- Numbered marks to the nearest 1/16", with a live bend diagram
- Bend Check warns you when bends are too tight or can't be bent
- Save the deduct and gain for your own benders

BOX FILL
