This block is used, either directly or indirectly via a quick release clamp, to securely and sturdily attach two Arca Swiss® compatible rails in a 90o angle to form the necessary L bracket for the infrastructure of a sturdy Multi Row Panorama Head.
The previous G103 block is depicted either utilized directly in my article Create a Multi Row Panorama Head, or indirectly in combination with an F69 QR Clamp in my article Create a Multi Row Panorama Head Ver. II
The New 90 degree Block
 |
| The major improvement of the new G103 block is the removal of extra material from the sides in order to minimize its mass, while maintaining its sturdiness. The new block weighs 48gr instead of the original 70gr. Although it does not seem much it is an actual decrease by 30% ! |
 |
| Some improvements have also been made in the block finishing... |
 |
| ...while a brand new laser engraved Hejnar PHOTO logo has been added in the front. |
Block Utilization
The G103 block is designed to match the slots and holes of the Hejnar PHOTO G10-xx multipurpose rails.
 |
| When attached on the front side of a G10-80 rail for example. |
 |
| It can either be used directly in order to form a sturdy L bracket by aligning and joining together two rails... |
 |
| ...or used in combination with an F69 Slot Quick Release clamp in order to form an adjustable vertical bracket for Panorama heads. |
