Mounting boxes for hollow wall installations

Combinations
Mounting boxes are easy to combine and install,
creating an efficient platform for the installation
of switches, outlets and other devices.

Box supports
Box supports PMR577 and PMR577.65 are used to
secure the boxes between the boards. No further
fixing of the boxes is needed, they are simply
placed in their final positions when the top board
layer is mounted in place.

Side nailing and wall clamps
The mounting box can be fastened to wall studs
by side nailing. Use nails with wooden studs and
screws with light metal studs. Wall clamps AS8.13
are used for attaching mounting boxes AU3.2 or
AU5.2 to a 12-13 mm thick board wall. The box is
pushed through the hole from behind of the
board, and locks firmly between the board
clamps.

Fastening with an adjustment adaptor
A box is attached to its base from the inside with
a PMR135 installation adaptor through the
opened center knock-out. The adapter is
delivered with a plug, that can be used to cover
the head of the screw. The box position can be
adjusted.
