I built a device to let me use the Piccolo on other (very strong) racks.

Basically it was a 6" square of steel (but you could use aluminum) with a threaded coupler in the middle (I forget the size of the bolt on the Piccolo knob) and to the sides were two steel drawer pulls that the latches went over. On the bottom, two pieces of aluminum flat bar went under the width of the rack. If the rack had a solid plate on top I had to drill a hole for the bolt on the bottom side of the threaded coupler.

If I recall correctly the bolt on the Piccolo knob was metric, and I had to special order a coupler from McMaster or MrMetric, but it was so long ago that I really can't remember.

Here's a diagram of it: "http://i50.tinypic.com/21j0mds.jpg". I built two of them so I didn't have to keep moving the Burley rack around, or buy more Burley racks.

Again, use this only on a strong rear rack, preferably that has triple struts.
