Mounting Puck System
The kit consists of four CNC machined pucks for each pannier (total of 8). The bottom 2 pucks on each pannier hold the shear weight of the pannier and are permanently attached with button head bolts. The upper 2 pucks on each pannier are the clamping force that holds the pannier to the side rack. They are tightened with a knob ... a quick couple of turns and the puck is loose enough to rotate and turn down to remove the pannier... no tools needed.MK750A mounts cases to any of our Happy-Trail SU racks and other racks built with 3/4" tubing.
