This rigid aluminum core is meant to be used with heavier core-wound Savage Infinity Solid Color Vinyl Backdrops. Simply insert the aluminum tube into the existing corrugated core to increase stability and eliminate sagging.
Please note: This aluminum core slides snugly into the standard cardboard core all Savage Infinity Vinyl Backgrounds are wound on and serves as a great full-length support to keep heavy rolls from sagging if left hanging on a backdrop stand between uses. We have not found it to be compatible with most background wall mount systems that use expanding support inserts at the ends of the core to rotate the backdrop up and down. (The inner metal core may continuously slip against the outer cardboard core when rotating.)
