In objtypes.inc the bankbox is defined as using this obtype number for the container: 0x0e40.
If you look in the itemdesc.cfg file in the \pol\config directory you will see this entry:
Code:

CanInsertScript ::canInsert
OnInsertScript ::onInsert
CanRemoveScript ::canRemove
OnRemoveScript ::onRemove
}
By adding this line:
MaxWeight <an integer with the max weight you wish banks to hold goes here>
For example:
MaxWeight 10000
You will define the maximum weight the bankbox can hold.
