Clamps are a  simple solution for connecting ducting to Inline Fans, Carbon Filter, Ducting Splitters or Air Cooled Reflectors. Fitted with a worm screw, tighten with a screw driver in a few seconds.  Clamps provide a secure connection, ensuring your extraction system remains securely connected.
The Clamps are made from strong, Stainless Steel  They are super easy to install and will last you for many grows to come. To install a clamp, you simple screw it open wide enough to fit over the end of your ducting, slip your ducting over the Fan/Reflector/Carbon Filter’s flange and screw it closed to ensure your ducting is fastened on tightly.

Available in a few different sizes to suit all ducting sizes. They are an efficient, cost effective method of joining ventilation equipment.

Clamp Sizes:

14-32mm (for larger water pumps)


PLEASE NOTE: 14-32mm Clamps are Stainless Steel, for use under water.

315mm clamping info

Clamps are an adjustable steel band that the user tightens with a screw. Most people generally know this kind of fitting as a Jubilee Clip which is often in the plumbers tool box. The premise is the same just on a bigger scale to suit ducting, not water pipes. The worm gear that adjusts the tightness allows a secure connection between ducting and fan or filter.

Many growers use ducting clamps in combination with Aluminium tape. This makes an even stronger join with advantages of both. The tape has a bigger surface area for joining and can go round and round as many times as you want. It can degrade after a while though so the Ducting Clamp will increase holding power of the join.
