The U-45 fits directly into the crossarm U-4 or UBA and has a mount to accept any camera platform accessory of the UST/UBS system. Ideal for ground level, low-angle shots. Displacement of the camera mount is 45 cm (18").
Alternatively, the U-45 can also be used to increase the height of the camera position with 45cm (18") when rotated in the crossarm joint, pointing upwards.
