The Kessler Multi-Angle Mounting Plate is designed to work in conjunction with the Kessler Low Profile Ball Head. The mounting plate can be attached in a 45° or 90° configuration and, coupled with the range of movement of the Low Profile Ball Head, will allow for configuring you camera at just about any angle you desire. The ability to mount to the LP Ball Head in a 90° configuration is ideal for doing vertical slider moves. With the optional Multi-Angle Cheese Plate, you can also attach various accessories and mounts; even another Multi-Angle Mount.
