Caution
The hole depth depends on the insulation layer thickness. If the
insulation layer is rather thick, you may need longer screws! If there are
hollow bricks under the insulation, make sure that your screws pass
through the whole dowel (50 mm) and fix the dowel reliably.
Make sure that the dowel holes have the required diameter. If the
diameter is too large, the dowels may get loose. Use some suitable
building adhesive to keep the dowels in place.
Make sure that the hole depth is sufficient too! The dowel length is 50
mm and the screw length is 90 mm.
Suppose that all the required cables have been carried into the drilled hole. Now
follow the instructions applicable for classic brick flush mounting. However, remember
that thermally insulated walls show less strength than classic brick walls.
Flush Mounting – Hollow Bricks
What You Need:
Brick flush mounting box, Part No. 9151001
Hole: (132 x 223 x 83) mm
Suppose you intend to install your
bricks. Note that the external side of the bricks gets damaged by cutting and the
dowels cannot practically be fixed into the thin internal part of the bricks. Therefore,
use the brick flush mounting box and follow the instructions included therein.
