Spectrum 150cm Tube Crossbars for Backdrop Support System (Triple Set FOR HALF PAPER ROLLS) - Bundle

The Spectrum Metal Inner 150cm Tube Crossbars for Backdrop Support Systems (Triple Set) are the ideal addition to electric motorised and manual roller support systems for half-width paper backdrops. Designed specifically to work seamlessly with triple-axis backdrop roller systems, these metal rods insert directly inside cardboard cores to provide essential structural support. By reinforcing your paper rolls from within, they eliminate central sagging, bowing, and creasing caused by gravity and ambient humidity. Perfectly sized for half-width paper backdrops and backgrounds up to 1.5 metres in width, this triple crossbar set ensures up to three background rolls remain flat, smooth, and perfectly level for every shoot.
