This Manfrotto Double Articulated Arm - 3 Sections Without Camera Bracket is the smaller of two Manfrotto Still Life Shooting Tables. It consists of tubular aluminum sections that you assemble, using the included Allen wrench.
The white translucent plexiglass mounts with touch fastener tape, and maybe tilted/bent upward and locked into place, to any angle up to 90°, for totally seamless backgrounds.
Although there is no provision for a curved foreground, the height of the front legs is adjustable, to provide altering of perspective.
