Dur-iFlex Optical Overlay offers the same aesthetic appeal as acrylic with visibly better performance. Providing uniform brightness, this thin, durable sheet allows Dur-iFlex to follow the contours of the most demanding application. Easily sheared or die stamped, Dur-iFlex is available in any size up to 48" wide x 50" long. HT High Transmission utilizes an advanced plano-convex optical pattern for superior lamp shielding.
