§Tools

Field tools. No account. No telemetry.

A self-score for the fabrication database, plus fast calculators for early sizing and shop or field layout.

Inputs stay in your browser. Results still require project-specific criteria and professional verification.

  1. Shop

    Database diagnostic

    Score a fabrication database across pricing, item structure, connector health, and documentation. Twelve questions. Answers stay in the browser.

  2. Airside

    Duct sizing calculator

    Size round duct by airflow and friction rate, check existing round or rectangular duct, and compare practical rectangular equivalents.

  3. Layout

    Field offset calculator

    Lay out two-elbow offsets, find the best two elbows to make an offset back-to-back, or solve the angle, radius, and spool for a known run.

  4. Rigging

    Gauge & weight calculator

    Estimate galvanized duct weight per foot, per section, and per hanger point from the size and gauge, with a typical low-pressure gauge hint.

  5. Support

    Hanger spacing calculator

    Estimate maximum hanger spacing, extra hangers near elbows and tees, and a suggested rod size for a horizontal metal-duct run.
