Master Bender Gold is the industry's leading and most precise conduit bending app for iPhone and iPad. Master Bender Gold is a conduit bending calculator for electricians. Master Bender Gold can also be used by plumbers and pipe fitters, who can enter their own tools into program. Master Bender Gold aids you in bending conduit raceways. It takes the math out of bending and allows you to concentrate on the task at hand. Master Bender Gold uses a more precise conduit bending algorithm than the cosecant method that is commonly used in the industry. This gives you more accurate bends with less waste. Master Bender Gold supports the following types of bends: * offset bends and rolling offset bends * three and four point saddle bends * stub 90° bends * parallel bends * segment bends * compound 90° bends Master Bender Gold contains information about: * gain & take-up * conduit layout * conduit weight & sizes * trig functions * fractions * bender methods * safety Master Bender Gold can bend and calculate most all types of conduit bends used today by electricians. Master Bender Gold supports numerous popular bending tools. Master Bender Gold supports hand benders, electric bender ie. sidewinder, 555, triple nickel, and hydraulic bending tools. Have a tool that is not supported? No problem! Master Bender Gold can work with any bending tool. Just tell Master Bender Gold the bending radius for your tool and you are ready to bend. Master Bender Gold computes bends using both feet/inches and metric measurements. Master Bender Gold makes it easy to bend pipes and conduit raceways regardless of whether you are a seasoned professional, studying to be in the electrical, electronic, engineering, plumbing, pipe fitting professions, or an hobbyist who needs to bend a few pipes. If you like Master Bender Gold, you may want to take a look at our other app: Master Electrician Reference™ (MER™). It includes a 29 page conduit bending manual. We also have a free version: MER™ Lite. More information is available at MasterSparky.com.

Bend conduit right the first time. Bend Aid is a professional conduit bending solver that uses the correct mathematical formulas for the shapes conduit is actually bent into — not the cosecant shortcut, not charts, not correction factors. An offset is not a right triangle. A right triangle has three straight lines; an offset has two bends and a straight section, and gain happens in every bend. The cosecant method has been used for almost 100 years as a "trick of the trade" because the correct math is too complicated to do by hand — it's "close enough most of the time," until a large bend radius or bend angle forces you to fix the bend. It's not your fault you were taught tricks. Bend Aid does the correct math for you. HOW IT WORKS Measure where the conduit has to fit, enter your dimensions, and use the answers to lay out the bend. Measure any two of the four right-triangle values and Bend Aid solves the rest — including the bend angle, which is not the same as the measured angle. Bend Aid solves the whole offset, from the start of the first bend to the finish of the second, and finds the smallest bend angle that fits between obstructions or supports — making wire pulling easier, reducing strain on conductors, and saving fittings, nipples, and material. WHAT BEND AID SOLVES • Offsets — including rack and concentric offsets • Saddles — 3-point and 4-point, with rack and concentric variations • Kicks — simple kicks, rack and concentric kicks, kicks to horizontal or vertical • Nineties — single 90s, back-to-back, rack, and concentric bends • Right triangles — enter any two values, get the rest • Find Bend Radius — measure your bender's true centerline radius • Chart Bender — solve bends using your bender's chart values EVERY ANSWER YOU NEED Bend Aid gives you all the numbers the old methods can't: where every bend mark goes, the total finished length, whether the conduit will still fit in the bender for the second bend, and the layout dimensions to cut and thread to length when needed. WORKS WITH ANY CONDUIT Bend Aid solves the centerline of the bends, so it works with any type and any size of conduit — EMT, rigid, IMC, PVC — and any bender, once you know its centerline radius. YOUR NUMBERS, YOUR FORMAT Enter and read answers in decimal inches, fractions to 1/16" or 1/32", or millimeters. Real-time validation catches entry errors before they reach the conduit. BUILT FOR THE TRADE If your job is skilled labor, you know tools are how the work gets done. Benders, tape measures, levels, and pencils are tools — Bend Aid is the tool that ties them together. Stop guessing, stop practice-bending, stop wasting time and material. Measure, enter, bend.
