Designed for the B10, B10 Plus, and B1X, the Profoto 10° OCF II Grid narrows the approximately 77° beam spread of the fixture for selective lighting. The grid attaches magnetically to the OCF II Barndoor or the OCF II Grid and Gel Holder and can easily be stacked with OCF II gels. Great for a hair light or accent light, this grid creates the narrowest beam spread of the grids that Profoto offers. There are also wider 20 and 30° grids available.
