Help with tube holder

[domination2580]

Ok so I ordered a tube holder for my 55 gallon tank dosing hoses. It said it would fit on rimmed tanks but low and behold, it doesn't fit. Any idea which ones will work? Anyone custom making any?

Ok so after thinking about it, I decided to try modifying it myself. I waited toolong to get one. I heated one of the bends up with muy logger and gently pried it apart.... it now fits over the rim but at a angle. The angle is fine for me sicce I tend to keep my water level high
