The Tremol-No is used for the Floyd Rose of my Suhr Rasmus.
There are plenty of youtube videos that you should familiarise yourself with before installation, as it helps with this kind of thing to really have a good grasp of what you're trying to achieve. Not only this, but Tremol-no themselves have taken care to describe best practice in the installation.
It may be necessary, depending on your guitar, to have longer clamp screws than what is already installed. This is not particularly mentioned anywhere, but my experience was that I'd have preferred to have a slightly longer screw for more security on the clamp.
In short, though, the Tremol-no is well designed, easy to operate, and pretty easy to install. Do also take care to investigate which clamp is required for you - there are a number of different models, and depending on your tremolo block you want to choose one that is compatible and that is going to be a good fit.
One last tip, don't forget (like I did) to keep your old spring clamp handy, in case you want to return the guitar back to factory condition!
