The 4-pack of RigWheels B-Cups includes four industrial grade car suction mounts with 5/16" studs that screw directly into the outer most holes of the optional RigPlate. Of the three different versions of suction cups that RigWheels offers, the B-Cups have more holding power in a straight pull than the A-Cups, and they also have less flex so the overall mount is a bit more solid.
