We recommend purchasing these clips in pairs and using 4 clips per 1 metre length of duct for normal installs.
Kair System 225 & 300 ducting ranges offer a perfect solution for installations where space is restricted. They are ideal for installations into ceiling voids, within walls, or under floors where compact dimensions are of greater importance than airflow rates.
Perfectly suited for ducting your Tumble Dryer, Bathroom or Kitchen extractor fan, Hydroponics, In-Line Extract Fans, or Cooker Hood. This item can be used to support long ductwork runs for a variety of purposes including whole-house ventilation, passive stack vent, positive input, air conditioning, HVAC, and Heat Recovery Systems.
