Mounting To A Wall Box - Extron electronics SM 3 User Manual

NOTE:
Observe all applicable building codes and local ordinances when installing the speaker.

Mounting to a Wall Box

1.
Place the wall box against the installation surface, and mark the guidelines for the
opening on the wall.
2. Cut the material from the marked area.
3.
Insert the wall box to check the size of the opening and fit. Enlarge or smooth the edges
of the opening if needed.
4. Feed cables through punch-out holes of the wall box leaving enough slack for the
speaker connections and secure them with cable clamps to provide strain relief.
5. Insert the wall box into the opening and attach it to the wall or stud, leaving the front
edge flush with the outer wall (see figure 3 below).
6.
To attach a wall box to wood, use four #8 or #10 screws or 10-penny nails. A minimum
of 1/2 inch (1.3 cm) of screw threads must penetrate the wood.
