The GAMMA support triangle allows quick and safe mounting on all types of flat roofs where the panels need to be properly inclined. To facilitate design and installation, the support triangle can be adjusted to three different inclinations: 20° – 25° – 30°.
On request, ST-24 and ST-26 support triangles can be supplied with a different inclination.
The support triangle can be combined with the G – H – I series profiles.
