The TransMount Camera Backing Base from Zhiyun-Tech provides a 0.6" height increase to allow for larger lenses to clear the gimbal's camera plate. Compatible with the WEEBILL LAB, Crane 3-Lab, and Crane 2, the Backing Base attaches to the camera plate of these gimbals with two included screws. You can then mount your camera on top using the gimbal's camera screw.
