Attach Mounting Plate to Wall

NOTE: Secure the mounting plate to the wall at both bottom 
corner holes drilled into the wall studs and/or drywall using either 
1/4-20 x 3" round-head bolts and toggle nuts or 1/4 x 2" lag 
screws.
Refer to illustrations in “Possible Wall Stud Configurations” in 
“Locate Wall Stud(s)” section.

No Wall Studs at Corner Holes (Figures 1 & 2)

NOTE: The mounting plate must be secured to the wall on at least 
1 wall stud as well as at both bottom corners.
1. With the support tabs of the mounting plate facing forward, 

insert 1/4-20 x 3" round-head bolts through both bottom 
corner holes of mounting plate.

2. Start toggle nuts on bolts from the back of the mounting plate. 

Leave enough space for the toggle nuts to go through the wall 
and to open.

3. Position mounting plate on the wall, making sure that the top 

of the mounting plate is aligned with the front edge of the 
upper cabinet.

4. Push the 2 bolts with toggle nuts through the drywall, and 

finger tighten the bolts to make sure toggle nuts have opened 
against drywall.

5. Insert lag screw(s) into the holes drilled into wall stud(s) in 

Step 2 of “Installation for No Wall Studs at Corner Holes” in 
the “Drill Holes in Rear Wall” section.

6. Check alignment of mounting plate, making sure it is level.

7. Securely tighten all lag screws and bolts.

Wall Stud at One Corner Hole (Figure 3)

1. With the support tabs of the mounting plate facing forward, 

insert a 1/4-20 x 3" round-head bolt through the corner hole 
that fits over the 3/4" (19 mm) hole drilled in Step 3 of 
“Installation for One Wall Stud at One Corner Hole” in the “Drill 
Holes in Rear Wall” section.

2. Start a toggle nut on the bolt from the back of the mounting 

plate. Leave enough space for the toggle nut to go through 
the wall and to open.

3. Position mounting plate on the wall, making sure that the top 

of the mounting plate is aligned with the front edge of the 
upper cabinet.

4. Push the bolt with toggle nut through the drywall, and finger 

tighten the bolt to make sure toggle nut has opened against 
drywall.

5. Insert a lag screw into the remaining bottom corner hole.
6. If installing on a second wall stud, insert a lag screw into the 

other hole drilled in Step 2 of “Installation for One Wall Stud at 
One Corner Hole” in the “Drill Holes in Rear Wall” section.

7. Check alignment of mounting plate, making sure it is level.
8. Securely tighten the lag screw(s) and bolt.

Wall Studs at Both Corner Holes (Figure 4)

1. Position mounting plate on the wall, making sure that the top 

of the mounting plate is aligned with the front edge of the 
upper cabinet.

2. Insert lag screws into both bottom corner holes.
3. Check alignment of mounting plate, making sure it is level.
4. Securely tighten the lag screws.

Prepare Upper Cabinet

1. Disconnect power to outlet.
2. Remove all contents from upper cabinet.
3. Place Upper Cabinet Template against the bottom of the 

upper cabinet, and attach with tape or thumbtacks. Make sure 
the template centerline aligns with the vertical centerline on 
the rear wall.

The “rear wall” arrows must be against the rear wall so that the 
holes cut into the upper cabinet align with the holes in the top 
of the microwave oven.

NOTE: If the upper cabinet has a frame around it, trim the 
template edges so that it fits inside the frame, against the upper 
cabinet bottom. The template has trim lines to use as guides.
4. Make sure the 10

points “D” and “E” on the template is maintained.
