1 X 100mm 1 x 125mm and 1 x 150mm Adjustable Stainless Steel Pipe Clamp Secure Hose Clip Inline Duct Extractor Fan Cooker Hood Ducting

These are excellent value, hard to complain really at this price point. They are highly adjustable, between 140-160mm in diameter. The metal itself seems decent quality and not overly thin, its steel and looks good new though doubtless will tarnish over time - doesn't really matter given this isn't a fixing you're likely to use anywhere highly visible. The screw adjustment is OK although its flathead whereas I would have preferred phillips or similar to prevent screwdriver slipping when tightening. However the internal screw itself is effective and doesn't slip on the notches when tightening, meaning you can cinch it as tight as needed. It is well made and makes installation easy.

Perfect size for securing my air extractor fan, no slipping or loosing just as tight as when I first fitted it, quality is outstanding, easy to use and great value for money

Do what they are supposed to.

Used for connecting interlink fan in loft from shower room, good fit strong connection, value for money, easy to fit.

Great value and does what they're supposed to. Bought for extractor fan instal in the loft and they worked like a dream.

Just the job for my project would recommend
