I have buy this to put additional cymbal pad on my Roland, i have looked for a long time something affordable that can work with Roland e Cymbals as they have specific mounts. 
I have also took Millenium MPS-500/750 Cymbal Clamp that can go to my Roland TDK 10/11 rack. 
Genuine Roland was to expensive for me so i found this solution and it works great. Now i have 3 cymbal pads and I'm happy. 
If you need something similar go ahead, it will work and it can send you nice amount of money.
