This is a replacement deflector for the Photogenic 24" reflector. It is a metal dome that deflects the light output of the flash head, and disperses it throughout the vast reflector for even light output without a hot spot.
The 3/8" Finger Nuts are used to securely lock the 9.Solutions 3/8" rods to different accessories. The 3/8" Connecting Nut is used to connect multiple 9.Solutions 3/8" rods together, allowing you to make longer rods.
Multiple rods can be used to create larger structures for rigging small cameras, lights, and a variety of other equipment.
