Professional Motorized Electric Heavy-Duty Wall/Ceiling Mount Multi Backdrop/Background Support System with 3.15M cross bars.
Powered by ACpower, with a cable length about 270 cm and a 210 cm wired remote control equipped with 3 buttons for each cross bar.
One end of the 47mm diameter aluminium shaft (with no holes) is inserted into the hole in the supporting mounting plate. The opposite end (with a hole) is inserted into the motor抯 mounting plate and secured with supplied nut and bolt. You can replace or set the background by rewinding it from the sleeve to the shaft, securing the edge of the background. Or put the background together with its sleeve on the shaft, compensating for the difference in the diameters of the shaft and the sleeve with suitable elastic materials (rubber, dense foam, foam plastic,etc.). These inserts between the shaft and the roll ensure the latter will not rotate on the shaft. Since the inner diameters of the rolls are not standardized, there is no other way but to use anti-slip, compensating for the difference in shaft diameters. Or, to change the backdrops, when installing the wall mounts remember to leave an additional 20mm clearance on the length of the aluminium rod to allow installation and removal of the rods.
This motorised multi backdrop system provides an automated solution, allowing you to have easy access to multiple backgrounds at any time.
