Kair Ducting Adaptor 110mm x 54mm to 100mm - 4 inch Rectangular to Round Straight Channel Connector for Converting to Different Size Duct Systems

A plastic adaptor that takes a 5" (125mm) flexible ducting hose, attached by a clamp, to a rectangular outlet that fits nicely in the hole left by a brick removed from the wall above a cooker in an old fireplace. The outlet was mortared in place and is hidden behind a hollow section of a bespoke mantelshelf. A most useful adaptor for a neat solution to an internal outlet. The plastic is sufficiently flexible to allow fitting in a tight space.

Very sturdy and well made the rectangular slot was smaller then expect when it arrived even thought it had measurements so make sure to measure before hand.It was great for helping me pump smoke machine smoke long the floor for my kids in the garden and house to play around and look spooky.

Wanted this to go on the end of our tumble dryer hose to poke out of the window. If you are planning to do this, also order the Kair Threaded Connector 100mm - 4 inch for Joining Flexible Hose to Round Pipe.Your dryer hose will screw into on end of the connector and the other end is a tight push fit into the ducting adaptor. Job done. Works perfectly and the items are very solid and should last for years.

Really great product! Be careful with the attachments as ours didn’t fit (I didn’t measure it) but I managed to glue it on…. Really great idea! I have cat locks on all the windows and they for through perfectly! Would also be great for a letterbox!

Had rectangular ducting but the hole in our wall was 100mm diameter. This converter worked perfectly and saved me making a new opening in the wall.
