The quickest, strongest way to mount your RotopaX.
Use with included base plate or remove plate to attach mount direct by bolting up through the bottom or down through the top.
Pack Mounts are milled from solid aluminum then anodized black and finally engraved. They use a 5/16" steel all-thread with a steel threaded insert (Helicoil) in the base. These are not cheap injection molded plastic parts that will fail when you are 25 miles down the trail!
