Simple Offset Pro

Pro calculator for electrical and HVAC offsets and bends

Simple Offset Pro focuses on one thing tradespeople value most on site: dependable measurements. It is a dedicated toolkit for electricians, HVAC fabricators, and installers who need clear numbers for bending cable trays, laying out square ducting, and cutting electrical trunking. By accounting for both run and set when determining trunking height, it helps translate drawings into practical, repeatable cuts and bends.

At its core is a fabrication calculator that covers square ducting, trunking layouts, and cable tray bends, reducing time spent on manual math. A Square Offset tool is provided for standard 45 degree work, ideal for common transitions and corner navigations. When you are mapping an offset path, the Offset Journey Calculator determines the travel distance so you can plan how far the route shifts before rejoining the original line. For more complex geometry, the Rolling Offset calculator calculates trip and run across four staple angles, 22.5, 45, 60, and 90 degrees, which are widely used in containment and ductwork workflows.

Unit flexibility is built in. You can switch between metric and imperial, using centimeters or inches as your job requires. That makes the app practical across teams and drawings that do not share the same measurement standard.

There are a few trade-offs to note. The angle options in the rolling offset tool are fixed to the most common values, which suits standard practice but may not cover uncommon angles. The feature set is focused on electrical containment and HVAC fabrication rather than broader mechanical or structural tasks.

If your day involves square offsets, rolling offsets, and consistent fabrication math, Simple Offset Pro brings the key calculators into one place. It helps you quickly derive run, set, trip, and travel, align measurements to site needs, and keep your layouts consistent across units and disciplines.
