INSTALLATION STEPS

1. In the centre of the intended position
of the cable outlet spigot, drill the
opening for the cable gland with a
circular cutter (Ø: 38 mm). Deburr the
hole with a round fi le or emery paper
(see illustration on the right).
2. Provisionally insert the casing lower
half into the drilled hole.
3. Mark out the positions of the three
fastening holes on the vehicle roof
(see illustration on the right).
4. At the marked positions, drill the three
holes with a twist drill (Ø: 2.5 mm,
20 mm deep).
Before starting to use Sikafl ex® 291
adhesive sealant, be sure to read
the Sikafl ex® Products safety data
sheet and technical data sheet in this
installation manual!
The prerequisite for good adhesive
characteristics is a clean, dry and grease-
free substrate. You should therefore use a
suitable cleaning agent to clean the area of
roof surface covered by the casing lower
half around the drilled hole, and then allow
the surface to dry thoroughly.
If the surface is painted, ensure that the
paint fi
nish is suffi
ciently well bonded
