Visual Products manufactures this lightweight lens rod support bracket for your Arriflex 16 SRI, SRII & SR3 camera. A precisely machined lightweight 15mm rod setup that provides a strong platform for your matte box, follow focus, zoom motors or other lens accessories. The new SR Lens Rod Bracket utilizes carbon fiber lens rods which reduce the weight of the bracket without compromising strength. The rods are held in the bracket by two nylon-tipped set screws. This system makes it easy to change the rods for use with different length lenses. The nylon tips of the set screws hold the rods firmly in place without damaging the carbon fiber (Note: if you put enough effort in, it is possible to damage carbon fiber even with a nylon-tipped screw)
