The tesa Ultra Power Lock Strips are equipped with the strongest Velcro from the tesa range, making them ideal as powerful fastening all-rounders for various projects in indoor or outdoor areas. Their exceptionally high adhesive strength is achieved through a special Velcro structure that resembles small mushroom heads. By simply pressing the two Velcro sides together, a stable connection is formed, accompanied by an audible click sound. The self-closing Velcro tape offers an impressive holding power of 4 kg per pack, thanks to its special locking mechanism and extra strong adhesive on the back, which can withstand high loads. Additionally, the strips are usable in extreme conditions, with high UV and temperature resistance from -30 °C to +90 °C, making them resilient against wind and weather. The self-adhesive tape can be frequently opened and closed and can be connected in any direction compared to ordinary Velcro fasteners, making it a particularly flexible and practical fastening solution. Not suitable for use on textiles, PE and PP plastics, wallpaper, and sensitive surfaces.
