plumbing, ductwork, or insulation. Locate installation
accordingly.
WARNING: ELECTRICAL SHOCK HAZARD! CUTTING
OR DRILLING INTO ELECTRICAL WIRES OR CABLES
CAN CAUSE DEATH OR SERIOUS PERSONAL INJURY!
AL W AYS make certain area behind mounting surfaces is free
of electrical wires and cables before cutting, drilling, or
installing fasteners.
Frame Housing
The exposed portion of the center wood stud must be removed
and the resulting cavity completely framed with wood. The
following steps are suggested. The actual procedure is
dependent upon the specific installation.

4. If necessary, cut rectangular hole in horizontal framing to
accommodate the PAC-GB1 Listed electrical box accessory
(not included).
5. Attach horizontal framing to each support block with two
#10 x 2-1/2" countersunk wood screws (not provided).
(See Figure 2)
