Enclose laser areas with ceiling or floor-mounted Flex-Guard® Curtain Systems. Durable, flame-retardant materials are suspended from coated, black steel tracks, and engineered for low-friction operation. Any configuration is possible using curves, by-pass rollers, and other accessories. When you need maximum flexibility for enclosing a laser work area or a temporary Class 1 laser safe work zone, choose freestanding, movable laser barriers.
