The 18° lens hood is longer than the standard 25° lens hood. MAC 600s fitted with the 18° hood fit only in the MAC 500/600 flight case, which measures 894 mm (35.2") from bottom (including wheels) to top on the outside. If the flight case is a pre-MAC 500 model, which measures 860 mm (34"), the fixture with the long hood will be damaged during transport.
If upgrading a MAC 600 to the snap-lock hood, the flight case must be modified slightly to make room for the snap-locks by moving both wooden support slats out 1 cm (3/8"). Replacement rivets (P/N 363058) for this purpose are included with the upgrade kit.
