Duct Precision: Measuring your Nordfab like a Pro!

Duct Precision: Measuring your Nordfab like a Pro!

When working with Nordfab metal ducting, we find that one of the most common questions that pops up is whether to measure the internal or external diameter.

Accurate measurements are key to ensuring your ducting fits perfectly and knowing where to measure can prevent costly mistakes.

Standard Measurement Practice

As with all ductwork, the standard practice is to measure the internal diameter. This ensures you get the right fit when ordering or replacing parts. Measuring the external diameter could give you an incorrect size, leading to mismatches.

Importance of Correct Measurement

With different sizes from 80mm – 710mm available, ensuring that your parts are compatible is crucial for a smooth installation. Measuring the internal diameter guarantees that all components fit together seamlessly and perform as expected.

The Key takeaway from this blog is: always measure the internal diameter when working with Nordfab ducting to avoid confusion and ensure compatibility with your system.
