Easy Offset is an easy to use program designed for the HVAC industry that calculates cut joints, elbow centerlines, and overall lengths for offsets of any angle. Saves time: -faster than using a calculator -improved accuracy -no multipliers or trig formulas to remember -reduces errors -minimizes cutting in the field and wasted material -use any angle -useful for field layout and detailing Types of Offsets: -round elbows -rectangular elbows with radius heel and throat -rectangular elbows with straight heel and throat -round taps on an angle -rolled nineties -wye branches
Duct Construction
This app helps determine duct construction and reinforcement options based on duct size and system pressure class. It provides condensed lists of suitable options, saving time spent on manual calculations and table lookups. Results are based on industry standards for galvanized steel duct sheets.
- Duct size range from 2" to 120"
- Pressure classes up to 4 in.wg
- Calculates duct weights per linear foot
- Determines required duct gauge and reinforcement spacing
- Clear illustrations for reinforcement types
- Simple and effective UI design

Get all duct construction and reinforcement options by entering the duct size and system pressure class. The aim of the app is to save time spent browsing through tables and texts to determine suitable options, by relying on the most widely used standards and providing a condensed list of available duct construction options. The results are based on galvanized steel duct sheets conforming to ASTM A653 & A924. The app does not cover all aspects of duct construction, as it is intended as a guide; Reliance on related standards, as well as good engineering sense is the basis for proper design. Features: 1. Duct sizes from 2" to 120" 2. Pressure classes 0.5 in.wg, 1 in.wg, 2 in.wg, 3 in.wg and 4 in.wg. 3. Provides the duct weights for each option per linear foot. 4. Provides required duct gauge and reinforcement spacing. 5. Clear illustration for each reinforcement type, as well as dimensions. 6. Simple and effective UI design. Roadmap / Upcoming updates: 1. SI units. 2. More pressure class options. 3. User will be able to save and retreive duct data for future reference. 3. More Reinforcement options, including tie-rodding.
