This is a Locking Tremolo Bridge Licensed by Floyd Rose. As you can see from the picture, it is thick and very sturdy (this is not one of the thin/weak Floyd copies). This bridge also features a Push-In style Whammy Bar. It includes the mounting hardware and accessories shown in the picture (Mounting studs, Anchors, Springs, Clawhook w/ screws, as well as the Whammy Bar).
