12 Month Warranty*Prevent cardboard core sagging and protect your paper backdrops with the Spectrum Metal Inner 150cm Tube Crossbars. Engineered as an essential internal support rod for both motorised and manual backdrop wall-mount roller systems, this heavy-duty aluminium crossbar slides directly inside the cardboard core of your backdrop rolls to ensure a perfectly straight, flat, and rigid setup.
By reinforcing your backdrops from the inside, these metal crossbars eliminate middle sagging over time—preventing paper creasing, structural warping, and uneven rolling. Consisting of two 75cm interlocking aluminium sections that join seamlessly to form a 150cm total length, this single set is purpose-built for 137cm (1.37m) half-width paper backdrops and custom rolls up to 1.5m wide.
Ideal For: Half-width seamless paper backdrops (137cm / 1.37m wide), vinyl backgrounds, and fabric rolls used on motorised electric or manual roller wall mounts.
Features
- Anti-Sag Core Protection: Reinforces the internal cardboard core of backdrop rolls to prevent sagging, bowing, and paper creasing during long-term storage or active studio use.
- Purpose-Built for Half-Width Backdrops: 150cm total length perfectly supports standard 137cm (1.37m) half-width paper rolls and seamless backgrounds up to 1.5m wide.
- Interlocking Aluminium Design: Features two 75cm high-grade aluminium sections with a smooth interlocking joint and locking screws for rigid alignment and easy disassembly.
- Universal Roller System Fit: Standard 4.8cm outer diameter accommodates expansion inserts for motorised electric units and manual chain-driven wall roller systems.
- Complete Hardware Kit: Includes all necessary assembly screws and hex tools for quick, straightforward installation out of the box.
