4. 

Secure the AB-2D to the electrical box or p-ring. Insert the

1/4

" long device screws into the oblong-shaped screw holes

on the top and bottom of the AB-2D. Note that the oblong
shape of the screw holes allow you to position the AB-2D so
that it is vertical. Position the AB-2D so that the screws are
aligned with the threaded holes in the electrical box or p-
ring. Tighten the screws using a phillips screwdriver. DO
NOT OVER-TIGHTEN. In some instances, you may need to
loosen these screws several turns to allow the AB-2D to fit
flush with the Decora cover plate. See 

(Figure 4)

.

5. 

Use the shorter plate screws to fasten the Decora cover

plate to the AB-2D. DO NOT OVER-TIGHTEN THE PLATE
SCREWS OR YOU MAY DAMAGE THE COVER PLATE. Line up
all the screws in the same direction for a finished look.

NOTE: 

Certain "old work" or "retro-fit" boxes, such as the

Carlon B225R, have a plastic "lip" which interferes with the
Decora plate screws. This lip prevents you from being able to
tighten these screws completely. To make the clearance nec-
essary for these screws, you must remove the parts of the lip
causing the interference. There are two ways to accomplish
this: 

1. 

Drill through the lip of the box at the screw points.

2. 

Cut notches into the lip with a pair of diagonal cutters.
