05. Fitting carrier rails
Insert the pre-assembled securing screw (M10 connection piece for roof hook profile) through the
roof hook slot. Rotate by 90° and insert into the mounting groove of the e.g. TF50+ carrier rail.
Connect TF50+ carrier rail to the roof hooks at the required height and tighten the screw.
Important: Please ensure all teeth of the type e.g. TF50+ carrier rail have engaged in the recess!
Start with the top or the bottom carrier rail. Align the screws with the fixing points (e.g. roof hooks)
and secure them. See Figure 87.
If required, extend the carrier profiles using butt connectors. Butt connectors enable ideal alignment
of the carrier rails.
Do no exceed a maximum carrier rail length of 3 rods (approximately 15,60 m) for continuous carrier
rails due to thermal expansion.
Prevent any water from collecting in the carrier rails to prevent frost damage.
