• Mark out the positions of the six fastening holes on the roof of the vehicle in a circular pattern.
Note:
The size of the holes and the choice of fastening screws to be used (not supplied)
depend on the type and thickness of the materials used in the roof structure. If the roof
panelling (plastic roofs) is suffi ciently strong, it is recommended that round head screws,
plain washers and self-locking nuts are always used to secure the glued mounting plate.

INSTALLATION AND CONNECTION
•
For very thin roof panel materials and insuffi cient support in the insulating material, through holes
(Ø: 5.5 mm) into the interior of the vehicle are necessary; galvanised M5 round head screws of
suffi cient length should then be used.
Make sure that you use a suffi ciently strong support that can accept the bolt tensile forces (large plain
washers or a complete reinforcing plate).
