Measuring instructions external Screen roller blinds

Long and trouble-free operation of a blind depends not only on the high quality of its workmanship, but also on its correct fitting and assembly. For the blind to fit perfectly, the chosen location must be correctly and carefully dimensioned.
The following auxiliary drawings must be strictly adhered to.


  • A - WIDTH This is the width of the window opening from the outside.
  • B - HEIGHT This is the height of the window opening from the outside.
  • C1, C2, C3 - Width of the visible elements of the window frame

Dimensions A and B will be the dimensions of the finished product.

*C1 and C2 are the width of the visible window frame elements (if C1<25 mm or c2<25 assembly impossible)
