Simply replace the foot nearest your kick pad with this and place the edge of the KD-10 base against the lip on the bottom. I have my kick sat on top of a thin rubber mat, so you might want to adjust the depth of the lip to suit your stack height. I also brace my rack against the wall, so the whole thing is rock solid and no longer creeps its way across my wood floor when I play.
The author remixed this model.
I just extended the bottom of this rack foot model to add a lip for the KD-10 base to fit against.
