Kair Elbow Bend Adaptor 110mm x 54mm to 100mm - 4 inch Rectangular to Round 90 Degree Bend Adapter for Converting to Different Size Plastic Ducting Systems - Female

Returned, didn't fit for what I wanted it for.

As I couldn't drill through outside wall for extractor I had to go through roof. Very little space between rafters and joists so using this was brilliant as the 220 x 90mm rectangular ducting was a neat fit and used adapter outside to go back to 150mm dia extraction pipe and flue.Brilliant job.

Used as part of a tricky static installation of an aircon. It did the job, although 'the job' involved a lot of ingenuity, foamed neoprene sheet, neoprene glue and ingenuity.

Good fit and value for money

Does exactly what it says 👍

A perfect fit for my vent sysytem.

Good product

Described as having a 6 inch diameter circular connector, but it's 5.5 inches. Pretty useless if you've already bought a hose of 6 inches in diameter and aren't prepared to 'bodge' a connection. I'll be doing just that because I'm 'bodging' parts together anyway, and this connector/adapter isn't the main component. Still, it's pretty poor show being out by half an inch. Oh, and whilst the thing will do its job once 'bodged' to a 6 inch diameter hose, the plastic is pretty thin and cheap. I wouldn't want to be pushing hot air through it. Oh, and it would have been nice if the delivery driver had actually delivered it to my address, not 2 doors down. The very first house he came to was number 3 which has no number on it, and has no one living in it, and right after that, there is a house with a number 2 on it, and next door to that, MY house, with a number 3 on the door. And he just left it at the unoccupied house, number 1. I'm moaning here because I've had about 6 deliveries over the past week or soand ONLY ONE DRIVER HAS ACTUALLY DELIVERED TO THE RIGHT ADDRESS. 4 HAVE LEFT ITEMS UNATTENDED AT NUMBER 1, AND I'VE GOT A MESSAGE SAYING IT'S BEEN DELIVERED, AND MY WIFE HAS HAD TO GO TO NUMBER ONE AND FETCH IT! ONLY ONE WHO TURNED UP AT NUMBER ONE, AND FOUND IT EMPTY, HAD THE BRAINS TO PHONE AND ASK WHERE I WAS. 'Number 3' I said. 'Two doors further up the road'. Do they not train delivery drivers how British house numbering systems work?
