The 14" Accessory Mount Bar from Custom Brackets is a support that accommodates either two DSLR cameras or one DSLR camera and a flash - or other accessories. It is made of black anodized aircraft aluminum with two cork pads running down the 14" length of the bar.
It is equipped with both 1/4"-20 and 3/8"-16 tripod mounting threads in the center. Each side has an imperial and metric scale, and one end has a built-in bubble level. The two center slots allow the d-clip screws to be adjusted from 1.75" to 11.0" apart. These 3 d-clip screws are included with the bar.
