If you are not so familiarized with floyd rose tremolos, your Bar broke or as in my case, the holder of the bar broke on yours, this is the perfect replacement.
The bar doesn't wiggle and can be tightened as taste.
You will have to open on the back of your guitar, place the bar holder piece on the socket in the back of your tremolo and screw on top of it the second piece and that's pretty much it.
Ultra simple and does the job pretty well.
i have to recommend it as it does the job and Im satisfied with it.
