The Chrosziel AC-401-121 is a base plate adapter designed for standard 19 mm rods. The plate is suitable for all cameras and is compatible with Chrosziel's patented V dovetail plate. The patented dovetail plate with QuickLock mechanism connects automatically to the camera quickly and easily. The plate mechanism prevents any unintentional opening, thereby ensuring permanent security of the device. By using a base plate, users can easily adjust the centre of gravity of the camera when mounted on a tripod.

In combination with the base plates, adjusting the centre of gravity on the tripod is very easy. The plates are supplied with 19 mm stainless steel rods (video standard). All 15 mm lightweight support accessories can be fitted using an adapter. For video cameras with different optical axes, the base plates are specially adapted.
