This 50-degree Profoto Softgrid for OCF Softbox tunnels the light of the 1 3x1 3' softbox forward while it helps control spill and directs the light only where you want it The grid has a clever design for mounting that entails slipping an outer skirt over front face of the softbox thus eliminating light leaks found in some units using touch-fasteners The fabric folds down to a fraction of its open size or can be folded while mounted along with the softbox
