ARRI had introduced the redesigned bottom plate 300mm/12" as well as two new bottom plates: 450mm/18" and__600mm/24". All three will have additional 1/4-20" threads beside the standard 3/8-16". Compared to the old bottom plate 300mm, the new one has its weight reduced by 25% while still being able to withstand the same forces. Its plate interfaces are extremely strong, thanks to heavy duty CAMLOCK fittings. The rear release pin system has been redesigned to be more comfortable.
