ELK-998 Alarm Decals provide a unique visual deterrent against robberies and break-ins. They feature three bright distinctive colors and are manufactured using the finest quality UV-resistant vinyl material and fade-resistant inks. The self-adhesive backing is weather resistant and can be mounted to virtually any smooth wood, metal, or glass surface. To further enhance the life expectancy of our decals, they are laminated with an additional clear vinyl protective material after printing. For maximum effectiveness, apply one decal to every accessible door and/ or window opening.
