Every now and the I get requests for “Warning Alarm System” decals and up until recently I didn’t have one that I liked. Thanks to the good folks at Elk Products I now have one that I can recommend. These come in either packs of 5 or 100. They measure 3.2 x 6.4 inches and look rather great.
The official blurb goes like this: 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.
