This background set consists of an electric background
 system and  The set is specially designed for working
 with fabric backgrounds, because background 
materials are usually not supplied with a solid 
cardboard core as is the case with paper backgrounds. 
Instead, the supplied aluminium rods are simply 
plugged together and pushed through the suspension
 tunnel of the background material for attachment to
 the expanders.
Design your work in the photo studio more efficiently 
with the electric motor background system
This photo studio equipment is a real work facilitation.
 No time-consuming moving of background fabric or
 background cardboard over chains! Simply use the 
included remote control and control each individual 
motor individually. For each motor, you have an 
individual channel available for control, which is displayed on the display of
 the wireless remote control.
