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 2N
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.
