No wonder I had issues going by quick installation/booklet... I thought literally can fit 4 inserts below fixed, & 1 above. I'll do way shown here 👍🏻 & put 2 I need above.
Why does it say on the website that it can be extended indefinitely when you can only add 4. I have a door that's 270cm tall and ordered 6 extensions but you can't fit more than 4? Great
