or KOMPACT 35 fr om 8 5/8” (22 cm) to 10 1/4” (26 cm), you can achieve 152 dif ferent
configurations.
The diagrams show the minimum and maximum dimension of the configurations you can
achieve with Kompact L or Kompact U.
Is there alread y an opening in the c eiling ?
From the 152 diagr ams, select one with smaller dimensions than the opening itself.

represented by numbers and point s).
Example: if you want to assemble the
external r ailing only on the left side of the
staircase (Diagr am 2), you must add:
2 + 4 + 3 = 9 balusters.
Therefore 2 additional external railings
must be purchased.
