7. Install a self-tapping screw and washer in each slotted mounting hole ( ) location
lined up with a wall stud:
a. Prepare the screw for installation by inserting it through a flat metal washer (1
inch [2.5 cm] outer diameter and 0.25 inch [0.6 cm] inner diameter).
b. Insert the screw and washer into one of the pilot holes on the wall.
NOTE: At this time, install only screws that line up with slotted mounting holes
on the MLM-WB+.
c. Securely fasten the screw into the wall until a gap of 1/8 inch to 3/8 inch
(3 to 9 mm) remains between the wall and the metal washer.
d. Repeat these steps until all self-tapping screws have been installed for slotted
mounting hole locations.
8. Install toggle bolts (if required) as follows:
a. While holding the plastic handle, collapse the toggle assembly and insert it into
the wall through one of the pilot holes.
b. Secure the toggle assembly by sliding the plastic washer down the plastic
handle into the pilot hole in the wall.
c. Using a cutting tool, cut off the plastic handle close to the plastic washer in the
wall. The plastic washer creates a threaded hole for a toggle bolt.
d. Insert a pan head bolt through a metal washer, then into the threaded hole,
leaving a gap of 1/8 to 3/8 inch (3 to 9 mm) between the washer and the wall.

Figure 10. Installing Toggle Bolts
ATTENTION: Potential Damage to Property. Install the toggle bolt
by hand; do not use a power tool. A power tool may create too much
pressure, causing the plastic washer of the toggle assembly to break. If
this happens, the assembly will fall into the wall.
e. Repeat these steps until all toggle bolts have been installed.
