Godox BD-04 shielding flap kit is 18 cm and on the front of a standard 7-inch reflector

Hi, I have it with Godox SL100 and it is compatible. With fv200 I don't know.

According to the manufacturer, this set fits the 7" (18cm) reflector. It could be that this item also fits all other 7" (18cm) reflectors.
