Snapped right onto my HD Bar without any drilling or extra hardware, which was my main worry. The RotopaX cans sit rock solid even on washboard dirt roads, no rattling at all.

The kit lines up perfectly with the SideBar slots and holds my water can tight even on washboard roads. Only gripe is the bolts are a bit short if you're stacking a thicker mount, so I had to swap them out.

Bolted this onto the HD Bar in about ten minutes and the RotopaX cans lock down solid with zero wobble on washboard roads. Only gripe is the hardware bag didn't include spare bolts, so a trip to the hardware store cost me an extra hour.
