Because with us the case is delivered dressing, had to be another solution to replace the belt (eventually the old times was to cut short and the blinds could not be left completely down). Went with this set really easy, thanks to a small enclosed mounting aid, the work can even run alone. The new belt looks now clean again from that point of transition from the old to the new belt is quite well covered with the supplied adhesive strips. Although one of these (and a short stretch of old belt) anyway just see if the roller shutter is fully up and no curtain hanging in front of it. There's even a trick, how to bring the belt so far out, that would be later no longer to see the mend, just search on YouTube, but I did not then too much work and the place does not bother me.
