Rotator D6/D8/D12/D16 has central M6 socket and anti-twisting sockets for attaching a foot plate. However, their large diameter limits the upward tilt of foot plate and also makes them vulnerable to dents and scratched. A Rotator Bumper is needed to protect the rotator and provides the clearance for upward tilt. Alternatively, a Quick Mount Mini Adapter System can be used.
To attach a foot plate, align the anti-twisting pins and place the bumper on the rotator. Then place the foot plate on the bumper, aligning the anti-twisting pins. Attach and tighten an M6 flat head screw to finish the assembly.
