Don't spend hours fiddling around with tricky clips trying to link up lengths of ducting and connect them to your extraction system, and there's no need to break out the duct tape either! These clever quick-release clips do the job for you. Using a worm screw design they are very easy to use and simple to replace. The result is a ducting system or extraction network that is stable, secure and strong with no 'weak spots' where the ducting joins together. Use them whenever you want to connect ducting to an extractor fan, carbon filter or silencer for a seamless connection that won't inhibit flow.
