Comments about Bogen Imaging Bogen - Manfrotto 3/8" Head Mounting Plate w/Locking Set Screws, fits 5/8" sockets, Super Clamp and Mini Clamp:
This is a replacement plate with bronze stud. Nicely machined and fits the SuperClamp perfectly. I use it to mount to my RRS B55 Ballhead to a Superclamp for calmping the whole rig to the roll bars in the open safari vehicles used throughout Africa.
