Installation
NOTE: Refer to local building standards and codes to verify that the installation will meet the regulatory
requirements. Observe all local and national building and safety codes, UL requirements, and ADA
accessibility guidelines.
Before installation identify the type of wall (masonry or non-masonry) and the location where the WMK 150 will be
installed. This determines the installation approach and type of fasteners needed to secure the plate to the wall.
1. Mount the Base Plate
Follow the steps within 1A or 1B, as applicable.
NOTE: The base plate can be installed over an existing
electrical outlet (see figure 2).
1A. To mount the WMK 150 onto masonry walls:
i. Hold the base against the wall, level it, and mark the
positions of four slotted mounting holes (indicated by
+ marks in figure 2). Set the plate aside.
ii. Using a masonry drill bit, drill 1¾ inch (4.4 cm) deep
pilot holes at the marked locations.
iii. Screw in ¼ x 1¾ inch masonry screws (not supplied)
until a gap of about 3/8 inch (9 mm) remains between
the wall and the screw heads.
iv. Align the slotted mounting holes of the base plate
over the installed screws, then slide the plate
down so the screws fit into the slots.
v. Verify level and position and tighten all the screws to
secure the plate flush to the wall.
Proceed to step 2.
1B. To mount the WMK 150 onto a non-masonry wall:
i. At the desired site locate and mark the wall studs.
NOTE: For ideal installation secure the base plate to at
least one wall stud with two screws (see figure 3).
Drywall KapToggles can be used for holes not
aligned with studs.
Always use the widest spacing of screws and
KapToggles.
The base plate can be installed over an existing
electrical outlet (see figure 2).
ii. Hold and level the base plate against the wall and mark
the positions of the slotted mounting holes that are on
the stud lines (see figure 3, indicated by + marks). Where
applicable, mark the mounting holes on the wall for
drywall toggles.
iii . If the cables are to be run behind the wall to the
WMK 150 location, mark the cutout area on the wall for
the signal cable access hole (see figure 3). Remove the base
plate and set the plate aside.
iv. Drill 1¾ inch (4.4 cm) deep pilot holes at the hole marks.
v. Cut out the marked area for cable access.
vi. At the pilot holes, screw in the screws until a gap of about 3/8 inch (9 mm) remains between the wall and
the screw heads.
