And I may have walked past these items 10s of times (or they might be new) but they were exactly what I was looking for.
More importantly they were cheap, £3.50 cheap to be exact! Double win.
This is how I made my easy kitchen door storage
The cupboard door I wanted to use them on was 600mm wide, but the actual cupboard frame was less than that as the door closes onto the housing. I’m guessing that this common as most kitchen doors are 600mm and they cover the whole frame.
To solve this problem, I removed the plastic end caps. (If you’re going to do this then be warned they were on really tight.) And then, I cut the rail very close to the perpendicular fixings that are used to mount the rail.
I did this on a drop saw but the metal is pretty thin and a hacksaw should do the trick. This then meant that the bar was cut to 555mm and this fit perfectly (5mm either side) into the frame for the door.
