You rotate the device on the tripod head, facing the appropriate marking. This is because the tripod heads are different sizes.FWIW, M122 is the designation of the M2 tripod for the M60; M3 of course is for the M2HB. My guess is that the flanges marked M122 and M3 respectively are centered on something on those tripods, and this is a riser adaptable to either tripod.
