Manfrotto Superclamp (Olde Fashioned) &nbsptype_On Camera Flash Provides 1:2 magnification without extensionThe Manfrotto Superclamp is a studio staple for a reason: it's sturdy, reliable, easy to use, and multi purpose. It'll grab boards, pipes, flashes and more, with a secure light stand stud receiver. This older Superclamp differs slightly from modern models in styling, lack of plastic padding on the clamp jaws, and notably: it does not have a 1 4" inner thread on its base.
