The Nanlite 150cm Parabolic Softbox Grid for Forza Para 150 Softbox mounts to the front of the softbox to minimize light spill and add directionality by tightening the beam angle. Grids are great for selectively lighting subjects without losing the soft quality of light produced by the softbox. This fabric grid swiftly and easily attaches to the softbox via touch fasteners and folds down flat for storage and transport.
