This caster based light stand has a 5/8 inch top stud. Caster base stands have a lower center of gravity that standard light stands and so are much more stable with heavy loads.
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.
