Window Alert 4-Inch Decals
WindowAlert decals help prevent wild birds from accidentally striking windows. Each decal has a special coating that reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, but birds see it as a brilliant glow much like a stoplight. To the human eye, the decals appear as frosted or etched glass. Window Alert decals may be used only on an exterior glass surface free of any overlay, tinting, film, or coating.
- Square or Butterfly design
- 4-inch Decals
