"I bought these runners to replace the poor quality nylon wheeled runners on a divan base and these are a far superior item .They were reasonably easy to fit in the confined space I had the only thing I would say is that you need both size of screws for fitting . Overall though I wouldn't hesitate to use these again they glide in and out easily and the locking features hold the drawer shut ."
I built an MDF drawer unit using 18mm and they were just over 1m wide and 25mm high and the rails held them no problems.
I did buy rails screws but they were bigger than the holes predrilled in the rails so had to make them bigger, i could only find 2 sizes and they were the smallest, other than that really easy to fit."
"An absolutely excellent product at a price normally paid for very much infereior "equivalents". Capable of supporting a fully laden tool draw, approx. 150kg, without difficulty. Smooth running and easy to install. I recommend this high quality product without reservation."
"These were bought to convert fixed shelves in a larder unit. They did a great job. Very easy to fit and very robust. The shelves are now easy to slide out, and with the amount of weight on them there is no fear of any of the shelves collapsing. Very pleased."
