Installation and connection
•For very thin roof panel materials and insufficient support in the insulating material, through holes (Ø: 5.5 mm) into the interior of the vehicle are necessary and galvanised M5 tallow drop screws of sufficient length should be used.
Make sure that you use a sufficiently strong support that can absorb the screw forces (large plain washer or complete reinforcing plate).

•Create the holes necessary to secure the mounting plate (Fig. C).
•In addition to the screwed connection, the mounting plate and roof duct must be bonded to the roof with adhesive and sealed. This is done using the Sikaflex® 291 sealing glue supplied, which is ideally suited for this purpose due to its broad range of adhesion.
Before you begin working with the Sikaflex® 291 sealing glue, make sure that you have carefully read the safety information for Sikaflex® products on page 34 and the technical data sheet on page 35 in this manual!
The prerequisite for good adhesive properties is a clean, dry and
For painted surfaces, it must be ensured that the coat of paint has the required adhesive properties with the substrate.
If the coat of paint is already loose or foliated, it must be removed down to a stable layer in the area of the adhesive surface. If you have any doubts concerning the adhesive properties, consult a specialist in painting and lacquering or the manufacturer of your vehicle.
Under certain circumstances, it may be necessary for you to improve the adhesive properties of the roof surface by
The procedure for glueing the mounting plate is as follows:
