USING AN EXTENDER BAR
Optional extender bars in various lengths (see page 5 for part numbers and page 50
for dimensions) are available to allow each Unity fixture to be held a certain distance from a
vertical mounting surface.
Each extender bar is manufactured entirely from aluminum to minimize weight and is
supplied with two sets of bolts, spring washers and standard washers to secure the fixture
swivel mount base (see note below).
There are four Ø7/16” (Ø11mm) holes in the backplate to allow for secure attachment to the
mounting surface. Wall screws are not provided; ensure the ones used are suitable for the
wall surface and have sufficient tensile strength for the combined weight and leverage of
the fixture plus the bar.
CONCEALED CABLING
Each extender bar features an access
hole on the top to allow power/control
cord access through the hollow bar
and backplate into the wall surface. A
waterproof seal for the cable access
hole is also provided.
Using the supplied washers
The supplied spring washers
help to maintain tension on the
bolts to prevent loosening.
Always place the spring
washer on each bolt
first and then add the
standard washer, before
inserting the bolt into
the clamp. This will
prevent the steel spring
washer from denting
the softer aluminum
body of the yoke.
