With the terminal of base and arm can be pipes, boards and other stuff 13-55 mm grasp. Manfrotto guaranteed 15 kg carrying capacity, in practice is much more ...
On the smooth side of the base there is a 1/4 "thread (female), in which the usual 1/4" can be attached screws. Interestingly, however, the hexagonal 16mm hole located in the base. You can attach a variety of 5/8 "or 16 mm spigot fix: round spigots are (also plastic handle) fixed with a screw, hexagonal (eg Manfrotto MA 037 Manfrotto MA 066 Manfrotto or 036-38) abide by the shape of the opening and a safety pin. So that nothing wobbles, it is here necessary to fix the screw. The safety pin also assures round spigots from falling out, but they can not fix.
With a double-hexagon spigot (eg Manfrotto 061 or 061RA) can be two Super Clamps combine, the jaws are free to grab something each. So that no longer are limited only for individual settings.
The Super Clamp is really good and gives the impression that it is best for years to do their duty. The plastic parts are all loaded on some places, the heavy lifting is done by solid metal parts. The disadvantage is that you will not get far without a small collection of spigots. This should be hexagonal (ie from Manfrotto ...) in order to really taking full advantage of the Super Clamp can. The course will cost additional money. On the other hand, the spigots can also be used for many years for all sorts of things.
I would recommend the Super Clamp recommend anyone looking for a reliable connection and this will also be flexible, both during construction and dismantling as quickly. That this is a buys in a fastening system may not necessarily be a disadvantage, because the system grows over time with the requirements with.
