The post screws to the top of the rig using the standard allen attachment screws. Adjustment for balance is right/left on the stage itself and fore/aft using the geartracks bolted to the underside of of the baseplates. Three baseplates are supplied, and they have enough holes in them to match most camera types and can take standard 1/4″ and 7/8″ camera screws. Trim adjustments are made by the black dials shown.
A friction lock secures the baseplate when the rig is balanced- but there is also an emergency lock recessed into the side of the stage to prevent release if the plate slips. Bars at the front of the top stage allowa J box and remote focus units/ redbytes etc. to be mounted.
£850.00 plus shipping. Also advertised on my site www.joebullensteadicam.com,(one more shot included).
