Industrial-strength extreme fasteners feature an all-weather, UV-resistant adhesive for reliable use on rough surfaces, including concrete and certain types of brick. Superior holding power meets the requirements of demanding applications without drilling, nails, screws or epoxy. Versatile construction can be used indoors or outdoors in temperatures between 0 degrees Fahrenheit to 150 degrees Fahrenheit. Easy-to-use design requires you to simply peel off the adhesive backing for immediate attachment.
