Choosing a ducting kit is the easiest and cheapest way to duct your cooker hood.

This page has our 100mm ducting kits, generally these vent kits are for tumble dryer and low power cooker hoods. All of our universal ducting kits come with fixing kits and instructions in every box. Please look below to see which parts make up our 4" kits.

If your hood is on an external wall then the GT41 kit is perfect for you. They include everything you need to duct straight out the wall. For more complicated ducting runs, that may require running along the top of cupboards then the GT43 kit will be perfect for you.

To find out if your cooker hood has a 100mm 4 inch outlet check the manufacturers' brochures, the product manual or if you’re buying a new hood from Glotech we've done all the hard work for you and tell you what kits fit your machine. You may also wish to have a look at the other sizes available 125mm (5") or 150mm (6"). Some of our kits use rigid flat channel ducting, though they don't measure 4", 5" or 6" we still say it is they our that size as it's designed for the air output for that size outlet.
