Planning your ventilation setup? Below you’ll find detailed dimensions, cross-sectional sizes, and technical drawings for both round and rectangular plastic ducting.
Use this guide to understand space requirements, ensure compatibility with fittings, and choose the right size for your installation.
Our round plastic ducting pipes are slightly bigger on the inside. That means most fittings (like bends or joins) slide into the pipe. If you need to join two fittings together, you’ll need a short piece of pipe to go around them.
Our rectangular ducting pipes are slightly smaller, so most fittings (like bends or joins) slide over the pipe. If you need to join two fittings together, just use a short piece of ducting to fit inside them.
