The Light Source M140 Cyc Track in black is a specialized, long-length aluminum extrusion designed for hanging and smoothly operating cyclorama (cyc) curtains, seamless backdrop fabrics, and other heavy drapery in theatrical, studio, and event production environments. The 120-inch (10-foot) length provides substantial, uninterrupted spans ideal for wide stage openings or large studio walls, minimizing the need for mid-span splices that could interrupt the smooth glide of carriers. Constructed from 6063-T5 aluminum alloy, this track offers an optimal balance of strength, lightweight properties, and formability, ensuring it remains straight and true under the significant load of wide, heavy fabrics. The black anodized finish provides durable corrosion resistance and a low-visibility, non-reflective surface that minimizes light spill and blends into dark theatrical surroundings.

This cyc track is engineered with a specific internal profile—compatible with M140 series curtain carriers—that allows carriers to glide smoothly along its length, enabling effortless opening, closing, and positioning of the drapery. The track is typically designed as a "reverse C" or similar channel that captures the carriers while providing a clean, finished edge. Its substantial length and robust construction make it suitable for permanent installations in theaters, television studios, and photography cycloramas, as well as for high-end touring productions where a flawless, wrinkle-free drape is critical. The track can be mounted directly to walls, ceilings, or structural framing, and multiple lengths can be joined with appropriate splices to create even wider runs.

In practical application, the M140 Cyc Track is the foundational hardware for creating professional, functional cycloramas and large-scale drapery systems. It allows for the seamless hanging of wide, unbroken fabric drops that serve as infinite backgrounds for stage productions, photo shoots, and film sets. The smooth operation ensures that the drapery can be easily managed for maintenance or scene changes. By providing a reliable, high-capacity, and clean-running track system in a long 10-foot section, this component enables designers and technicians to achieve professional theatrical and studio effects with efficiency and reliability.
