Cyflect Fire Extinguisher Sign, 4a ^2x17a ^2 - Glows and Reflects Enables you to locate the fire extinguisher in the dark with intense glow and amazing reflective properties. Patented Cyflect is the only product where 100% of the surface area both glows and reflects. Cyflect products are non-toxic and waterproof. The sign is visible through fog and smoke, and unlike glass-bead material, will reflect equally well wet or dry and from oblique angles. With an industrial adhesive backing, installation is easy - simply peel and stick.
