The Spinner by Cleanscamerasupport allows you to rotate the camera on your cart by 360 degree so you can easily reach every side when you have to change your setup or have to pass through door, elevators etc.
The beauty in it is the simplicity. Easy to use and maintain.
Depending on your cart, you will need to mount it on the Riserplate by Cleanscamerasupport. Which is sold separately.
