I ordered the tape because I've built a plasterboard wall in the office, the skirting board but could not be plugged, since underfloor heating is in the floor. The metal profile had therefore be fixed with the adhesive tape on the carpet. The 5 cm width are exactly the width of the sheet metal profile that fits exactly. Since I have pasted the entire 5 meters, which holds also like bomb. When preparing the profiles you have noticed how the tape claws into the carpet.
