or the distance between the wall rails (C) for a wall
mounted system.

5.2.3 Attachments for curves
Rail curves are only possible for ceiling mounting.
Minimum requirements:
Figure: Minimum three attachments must be
mounted. One in each joint section and one in
center of curve radius.
For joining curves with other rails of same profile a
Joint Set is used.
