The height adjustment of the sliding of my Ikea closet eventually collapsed.
Ikea was so kind and did not provide any replacement parts.
When I disassembled the broken part, I was a little shocked how poorly it was designed and what trouble it caused - it nearly broke my TV :(((((((
So this little part is here to help prevent any further collapsing maybe it will help you too :)
I uploaded different heights, according to your need, if adjustments are necessary please use the tool DesignSpark Mechanical to adjust the rsdoc file.
