These professional quality Fast Clamps are perfectly designed for joining two rigid items such as fans, filters and silencers.
The clamps can be tightened via the two bolts and the neoprene lining will help to reduce noise caused by vibrations, we still recommend tape to ensure air-tightness.
It should be noted that these clamps are not recommended for joining lengths of ducting due to the flexible nature of aluminium ducting. Instead we would recommend using a Coupler and Ducting Jubilee Clips.
