Step 3:
Lightly loosen the
¾”
bolts securing the speaker adapter plate to the support
arm’s pivot rod. The support arm should be able to rotate easily without
binding. Attach the speaker adapter plate and support arm assembly to the
appropriat
e mounting holes of the speaker using the manufacturer’s
suggested screws and washers. The support arm should face the lower end
of the speaker. Tighten these fasteners permanently. If threaded inserts are
not included on the speaker, consult the speaker manufacturer for proper
mounting procedures. (Figure 3).
Step 4:
Lift the speaker and support arm up to the mounting plate and insert
the arm through the end of the mounting plate with the cross slot
(Figure 4). Line up the support arm’s threaded hole
with the cross-slot.
Insert the 5/16” hex bolt with the pan locking washer through the
mounting plate’s slot and into the th
readed hole of the support arm
(Figure 4). Be sure the pan locking washer is seated vertically outside
the slot.
