Designed for large venues, the Wireline uses thin steel cables up to 29 feet instead of black drop to lower the screen to an appropriate viewing height. The extra step of finishing the screen with trim is also eliminated because the Advantage line of projection screens is designed with ceiling trim already in place. Once the screen is installed, the screen's trim conceals the rough opening eliminating the need to complete additional trim work.Sliding installation brackets make it easy to attach the screen housing to the structure above the drop ceiling. Tensioned screens ensure the smoothest surface possible, and the Wireline™ Advantage® screen features simple in ceiling installation.
