ARRI Support Plate 600 mm with the adjustable 19 mm studio rod support brackets (RSB-19), for very long lenses such as the Angenieux 24-290/28-340 or Alura 45-250 with 2x extender.
Its plate interfaces are extremely strong, thanks to heavy duty CAMLOCK® fittings in 3/8-16“ and 1/4-20“. The rear release pin system has been redesigned to be more comfortable and reliable.
