at roof support consist of two rails, triangular supports and one wind brace. The number of triangular supports
depends on the number of collectors. Use one support for each collector. One wind brace is suf

cient up to the
rail length of 6.15 m.
• lay two rails on the mounting surface and insert the nuts into their grooves
Distance between the rails = 1720 mm
The diagonals between the base rails must be of the same length:
D1 = D2
03-C – Triangular support
04 – Aluminum rail
• the triangular supports come screwed together with two bolts. Fix the loose support ends with a bolt. The
distance of the
