kitchen pull out bin 600mm hafele
and it will find you some.
I had assumed there would be a Blum or a Kessebohmer version but I don't see one. They're other brands I am happy with for more expensive extras full of complicated pivots, sliders and cunning springs. I happen to have used a B&Q "Cooke and Lewis" drawer when short, and the quality was noticeably worse (it went in the skip). We simply couldn't get it to run as well.
For a kitchen bin, these high-tech pull-outs can be rather a lot of money, so I'd be annoyed with one where the quality was not good. Like kitchen drawers, if you go for a soft-close, glides-like-velvet Blum, it might cost you £50 or so, but it will last for years. You'll be annoyed by a product that sticks, rubs or grates long after.
Sometimes you can get a good quality one at a reduction where a designer has ordered it but the customer changed their mind after delivery, or a supplier is clearing last-years stock.
