Detailed description and uses

The plate is made from CNC-machined aluminum, which delivers precise hole placement and flatness across the surface. Because the holes follow the industry standard 3/8" size and are spaced every 1", you can mount common film accessories without custom drilling or modification. The four corners are counter-sunk at 82 degrees on one side to accommodate flush head fasteners or to help the plate sit neatly against other surfaces.

Additionally, the product title indicates it functions as a China ball bracket and includes an E27 socket, which supports using lamps or fixtures that require that socket type. Overall, it helps organize and secure gear in film and video setups where a robust, hole-patterned plate is needed.
