Bendmark: Conduit Bending

Bendmark is a conduit bending calculator for electricians and apprentices. Pick your bender once, type the measurement the way you read your tape, and get every mark in big, clear numbers, with a to-scale drawing of the bend and step-by-step bending instructions. Works for EMT, IMC, rigid (GRC) and PVC conduit.

MARKS FOR THE BENDER IN YOUR HANDS
Most conduit bending apps use one rule of thumb for every bender. Bendmark uses your conduit bender's real centerline radius, deduct (take-up) and gain, so the marks match the bend you actually make. Choose from 260+ hand, mechanical, hydraulic and electric bender shoes, from 1/2" to 4", each linked to the manufacturer's spec sheet, or add your own bender from a test bend. Prefer the textbook? Switch to field multipliers and get the same numbers as the bending chart printed on your bender.

EVERY COMMON CONDUIT BEND
• Offsets and box offsets, with shrink and distance between marks
• Rolling offsets (true offset and roll angle) and parallel offsets for a rack of conduit
• 3-point and 4-point saddles
• 90° stubs, back-to-back 90s, segmented 90s and concentric 90s
• Kicks and kick 90s
• Multi-bend layout: several bends on one length of conduit, every mark from the end, cut length and the NEC 360° check

BUILT FOR THE JOB SITE
• Big numbers you can read from the ladder, and a large-text mode for bright sun
• A glove-friendly keypad that takes fractions: 12 3/8, 4'6 1/2" or 150 mm
• Round to 1/8, 1/16 or 1/32 of an inch, or work in millimeters
• Keeps the screen on while you bend, and reopens right where you left off

SEE THE BEND BEFORE YOU MAKE IT
• A to-scale drawing of the conduit with every mark numbered
• Step-by-step instructions: which mark goes on the arrow, when to roll the conduit, what angle to bend
• Animated guides that show each bend being made, with your numbers
• Warnings when a bend is impossible for your bender, the bends would overlap or the run won't fit on one length of conduit
• Shrink, travel, gain, developed length and cut length

MORE ELECTRICIAN TOOLS
• Angle gauge: lay the phone on the conduit and it vibrates when you reach your angle
• Tape math: add and subtract feet, inches and fractions
• Reference tables: offset multipliers, shrink per inch, bender deducts and NEC minimum bend radius
• Save jobs and share a mark sheet as an image or PDF with your crew or apprentice

LEARNING TO BEND PIPE?
Apprentices get the same marks and instructions as the pros, plus the animated guides that show what the arrow, the star and the center mark are for and why you roll the conduit between bends.

PRICING
Bendmark is free to download with offsets, box offsets, 90° stubs, back-to-back 90s, kicks, tape math and the reference tables. Pro adds saddles, rolling and parallel offsets, segmented and concentric 90s, kick 90s, the multi-bend layout, the angle gauge and your own benders. Try Pro free for 14 days without entering payment details, then unlock it with a single one-time purchase. No subscription and no ads.

PRIVATE AND OFFLINE
No account, and Bendmark never sends your jobs or benders anywhere: they stay on your phone. The conduit bending calculator works fully offline, in basements, tunnels and anywhere without signal. The only time the app goes online is when Google Play handles the Pro purchase.

Bendmark is a calculator. Benders, conduit and technique vary, so check your marks with a test bend before you cut. You are responsible for code-compliant work.
