This guide is for anyone needing to secure 6-inch (150mm) flexible ducting, such as for extractor fans or ventilation systems. The key benefit is a reliable and durable connection that prevents leaks and ensures efficient airflow. A potential consideration is that these are specifically sized for 150mm ducting, so precise measurement is key. These clips offer a strong, worm-drive mechanism for a tight seal on 150mm flexible ducting, manufactured to high standards for both domestic and commercial applications.

These clamps are specifically designed for 150mm (6-inch) diameter flexible ducting.
They are manufactured from W1 Mild steel, which is zinc-coated for basic corrosion resistance.
You use a screwdriver to turn the worm screw located on the side of the clamp band. Tighten it clockwise to secure the clamp.
While they offer zinc coating, prolonged exposure to harsh outdoor elements may lead to corrosion over time due to the mild steel construction. For highly corrosive environments, stainless steel alternatives might be more suitable.
A worm drive clamp has a screw mechanism (the 'worm') that moves along a threaded band, allowing for precise and secure tightening around a hose or duct.
The bandwidth of these clamps is 12mm, which provides a good surface area for gripping the ducting.
Yes, other sizes and accessories are typically available from B&Q for different ducting requirements.
Ensure the clamp is fully encompassing the ducting and fitting. Check if the ducting is properly seated. Verify the clamp size is appropriate for the ducting diameter. If the screw mechanism feels stripped, the clamp may need replacement.
Tighten the worm screw further. Ensure the clamp is positioned correctly over the connection point. Check that the ducting material is not too thin or damaged, which might prevent a secure grip.
Ensure you are using the correct type of screwdriver (flathead or Phillips) that matches the screw head. Clean any debris from the screw head.
For mild corrosion, you can try cleaning with a wire brush. If corrosion is significant and compromises the clamp's integrity, it should be replaced to ensure a reliable seal.
