Attach the Gibraltar SC-RM105 10.5mm R-Class Floor Tom Rail Mount to your floor tom, and voila! This piece of hardware is really three parts combined into one device:The U-shaped arm slides into one of your existing floor tom leg mounts, while the other end rests on the shell. This end is equipped with a thick rubber stopper to prevent any damage. The L-shaped arm holds the mounted tom. The clamp holds both of these arms together, and both sides are totally adjustable so you can customize the placement of the drums to your personal liking.
