The BEX-1.75 is used to extend the height of the vertical arm on our Omni-Pivot Packages or the PG-01 Vertical Arm. This is useful for certain camera-lens combinations when one wants to shoot the zenith (pointing straight up). Though not necessary for most flat-projection, composite panoramas that most nature photographers create, those shooting spherical or “virtual reality” images will find this useful.
The BEX-1.75 can either be attached to a B2-FAB, B2-Pro or B2-LR-II clamp for quick release convenience, or it can be attached directly to the MPR-192 Rail. Use the two included captive screws for either application.
