Can I not join the previous very bad review. Have bought the FlexFrame padlock holder because the holder is a lock with supplied Katasthophe with my master lock. This one (especially with the 2 different sizes) fits not only wonderful even without the rubber casing to remove and holds both the castle and the frame super safe. No rattling, no longer afraid at curbs or cobblestones. I think it is mainly a question of whether you follow the operating instructions or not ... The interior rubber jacket can slip because nothing. The only complaint is that the whole thing a little "thick" applying. The holder is attached with me back to the side, because the lock is too long to hang it "in" the frame. So it stands but a little too much, so I'm on the other hand almost to the leg while pedaling. It's tight, but it comes, so I'm just a star deduction, since it does not really bother, but just almost ...
