MLM-WB+ • Installation 11
Mounting the MLM-WB+ on a Nonmasonry Wall
NOTE: On nonmasonry walls, the MLM-WB+ must be attached to at least one stud.
The recommended installation suggests that the wall box be attached to two wall
studs or to a concrete or masonry wall.
1. Locate the wall studs in the area where you will install the MLM-WB+, and use a
pencil to mark their locations on the wall.
2. With the help of at least one other person, hold the MLM-WB+ against the wall so
that the mounting holes line up with the studs as follows:
• If two wall studs are accessible, align the slotted and round mounting holes
on the back of the MLM-WB+ with the studs as shown in figure 9 (choose either
option A or option B).
• If only one wall stud is accessible, align the round mounting hole in the
center of the MLM-WB+ with the stud (option C in figure 9).

3. Use a carpentry level or similar tool as a guide for leveling the unit.
4. When the MLM-WB+ is level and properly aligned with the studs, mark the locations
of the slotted and round mounting holes on the MLM-WB+ (indicated by + marks in
figure 9).
If you are mounting the MLM-WB+ to only one stud (option C in figure 9) also mark
the slotted holes indicated by the four X marks to add toggle bolts to increase the
stability and strength of the installation.
5. Set the MLM-WB+ aside.
6. Drill pilot holes in the wall at the locations you marked in step 4.
• If drilling into a stud, make each hole 1.75 inches (4.4 cm) deep.
• If drilling into the wall where no stud is present, make each hole
through to the hollow part of the wall.
