1. Measure the Space

Start by measuring the area where you plan to install the 20mm duct corner. Accurate measurements are crucial for a snug fit.

“How do I measure?” you might ask, “Do I just use a ruler?” No, a measuring tape gives you the best results!

“Is it safe to use this knife?” Absolutely! Just wear your safety goggles and gloves, and you’ll be fine!

3. Fit the Duct Corners

Now it’s time to fit the 20mm duct corners into position. Slide them onto the ends of the cut straight ducts. They should fit tightly.

“Should I glue them?” Good question! You can use adhesive or duct tape to hold them securely.
