Quick-release plate with 3/8″ thread for quick-release unit BALSO for SUPERBALL (fits also other quickrelease units).
The removed edges allow a smooth and quick insertion into the quick-release unit. When using Hasselblad cameras,
the small, eccentric screw of the quick-release plate BALPU can be unscrewed some bit, so that the plate is fixed safely
onto the camera and doesn’t twist.
