Built for the way you bend
Everything between the tape measure and the bender, on the phone already in your pocket.
Your bender, not a chart
Pick your bender and shoe from 34 built in, and every mark comes from its centerline radius and deduct, so the numbers match the way that shoe really bends. Not listed? Enter the deduct and gain printed on it.
Marks you can bend from
Each mark says how far from the end it goes, which way the hook faces, what to line it up with on the shoe, and when to roll the conduit.
Know before you bend
If the bends would overlap, run off the end, or leave too little straight for the shoe to grip, BendMate flags it in red or orange before you waste a stick.
Every common bend
17 bend types: offsets, rolling and parallel offsets, three- and four-point saddles, 90s, kicks, and compound and segmented 90s.
A whole stick at once
Lay out several bends on one conduit, every mark measured from the same end, with the cut mark and the cut length.
Racks that stay parallel
Bend a rack of conduits through the same offset, 90, kick or saddle, all one size or mixed, and get each conduit’s own marks.
Your phone is a protractor
The level reads a bend’s angle with the phone’s tilt sensor. Lay it on the straight part to zero it, then on the bent leg to read the angle.
Share it or print it
Send a link that opens the same bend on the same bender, or print a clean cut sheet for the crew.
Works with no signal
Basements, tunnels, new builds: once it has loaded, BendMate runs without a connection. Your benders and saved bends stay on your device.
Type it the way you say it
A number pad that takes 14 3/16 or 1' 2", rounds to the fraction you work in, and switches to centimeters.

Questions electricians ask
What is BendMate?
BendMate is a conduit bending calculator for electricians and apprentices. Pick your bender and conduit size, enter your measurements, and it gives you the marks, shrink, cut length and bend angles for offsets, saddles, 90s, kicks and more. It runs in a web browser and works offline.
How is BendMate different from an offset multiplier chart?
A multiplier chart treats every bend as a sharp corner. A real shoe bends on a radius, which uses a little less conduit. BendMate works every mark out from your bender’s centerline radius and deduct, so its numbers are slightly smaller than the chart’s and match what the shoe does. You can switch to the multiplier method if you want the textbook numbers.
Which benders are built in?
34 hand, mechanical, electric and hydraulic benders from Current Tools, Gardner Bender, Greenlee, IDEAL, iToolco, Klein Tools, Milwaukee, and Southwire, with 400 shoe and conduit combinations for EMT, rigid, IMC and PVC-coated rigid. There’s also the multiplier method, for textbook numbers with no bender.
Does BendMate work offline?
Yes. Once BendMate has loaded, it works with no signal, even after you close it. Add it to your home screen and it opens like any other app.
How much does BendMate cost?
$5.99, paid once. That gets you every bend type, every bender, the level and every update.
Why isn’t BendMate in the App Store or Google Play?
BendMate is a web app: it runs in your phone’s browser, so the same app works on iPhone, Android, tablets and computers, and it updates itself. Add it to your home screen and it opens like any other app, even with no signal.
Bend it right the first time.
Your bender, your measurements, marks you can trust.
