Flat profile for practical and visually appealing coverage of connection joints or corner connections, suitable for outdoor and indoor use. Both variants, both as a single profile and on the roll, have predetermined breaking points at a distance of 10 mm, which allow the profile to be shortened without tools. The version on the roll also offers a self-adhesive function for easy and problem-free processing. The packaging form as a continuous material makes it easy to transport, protected from scratches and dust and almost free of cuts.
