Attaching the Mounting Bracket
Assembly to a Pole

A) Thread NYLON TIE thru Tie Slots and around
pole to TEMPORARILY hold the Mounting
Bracket Assembly in place on pole.

B) Insert (4) MOUNTING CHAIN HOOKS
and attached WING NUTS through
the most appropriate top & bottom
Bracket Assembly slots.

C) With Hooks fully extended, attach
one end of MOUNTING CHAIN to
one of the Top Mounting Hooks.
Pull the Chain tight to Pole and then
attach shortest link to corresponding
Top Hook. (To keep chain from being
jammed by the hook, place link on
outside of the Hook.) Spin Wing Nuts
down evenly, enough to keep the
Assembly in place.

D) Repeat process for Bottom Hooks
and Chains.

E) Hand tighten all Wing Nuts evenly,
ensuring Mounting Bracket Assembly
is difficult to rotate on the Pole. Then
“tap” the chain sharply to remove any
slack and fully re-tighten all Wing Nuts

IMPORTANT: HAND TIGHTEN ONLY.
EXCESS TIGHTENING MAY CAUSE
HOOK ENDS TO SPREAD.

Speaker Assembly Angle Adjustment
and Locking Procedure

A) Loosely Insert 2 (#10) AXLE SCREWS to both sides of Stationary Mounting
Bracket and into the Speaker Assembly Bracket. This will provide safe retention
of the Speaker Assembly.

Bracket to rotate the Speaker Assembly to desired angle. Front Tabs on each
side will then engage ADJUST ANGLE HOLES on the Mounting Assembly.

C) Once angle is selected, insert 2 (#10) ADJUST SCREWS into Adjustment Angle Holes
directly below the Tab/Holes selected. Finally, tighten all four Screws SECURELY.

IMPORTANT: ALL FOUR (2 AXLE & 2 ADJUST) SCREWS MUST BE IN PLACE
AND FULLY TIGHTENED FOR ASSEMBLY TO BE SAFELY SECURED.
