Hackers Help: Bygel – Fintorp and Pax?


Ok, I normally use a 1 door Pax as storage for my vacuum cleaner, broom, cleaners and similar.
On the door I used to have (badly glued) one of those multi pocket things to keep small things organised. It fell off today.
I was thinking about placing a rail (Bygel or Finntorp) screwing inside the Pax door and then place a new multi-pocket thing.

Has anyone screwed anything inside a Pax door?
Will it last?

Thanks for the help!
