Flex Seal Super Wide Duct Tape is no ordinary duct tape. In fact, it's up to 300-percent wider than standard duct tape. Tough, reinforced backing and powerful, thick rubber adhesive provide maximum bonding strength (when applied on compatible surfaces). Specialty duct tape is removable, repositionable and can be torn by hand (both vertically and horizontally), so there's virtually no waste. Plus, it is water-resistant, weather-resistant and UV-resistant, holding up to various environments. Super-wide duct tape is perfect for reinforcing boxes, general household repairs, DIY projects, sealing drafty windows and doors, tears in furniture or fabric, securing cords and wires and more. Tape may not bond to certain siliconized material, water-repellent surfaces, some porous surfaces or dirty/greasy/oily surfaces. Tape is not intended to be applied to wet or continuously submerged surfaces. It should not be used as an electrical tape.
