if you want to lock it down permanantly, a block of wood would probably do the trick. or maybe two, so you can't dive OR pull up.
...but then, i don't know if they would slide around, or what.
but, if you want the functionality of being able to lock down your trem, locking it to dive-only mode, or full floating, all with the turn of a few thumb screws, get a T-No
