6 . Pass the two legs of the U-bolt through the following parts in the order they
are listed below:
a
. The slotted holes on the back side of the PMK 350 mount plate (then
around the ceiling pole)
b . The round holes in the rubberized contoured base
c . The round holes in the L bracket
7 . Place the rubberized contoured base against the pole and opposite the back
plate. The pole should fit snugly into the depression in the center of the
contoured base.
8 . Align the two holes in the bottom of the L bracket with the two slotted holes
in the base of the PMK 350, on either side of the opening for the pole; and
attach the L bracket to the base by inserting the two provided 6-32 x 5/16"
screws through the aligned slots. Tighten the screws slightly; you should
still be able to slide the L bracket to adjust it as needed. (See the illustration
below.)

9 . Move the PMK 350 up to the desired location on the ceiling pole, as close to
the ceiling as desired.
10 . Secure the L bracket to the U-bolt, using the included hex nuts. Hand-tighten
the hex nuts, make any final adjustments to the PMK’s position, then tighten
the hex nuts securely, using an 11/16" deep socket or box-end ratchet wrench.
N Be sure to tighten the hex nuts securely enough that the PMK 350 does not slide
down the ceiling pole. It is recommended that you use a socket wrench to tighten
them.
11 . Tighten the L bracket screws securely, using a Philips #2 screwdriver.
12 . Secure the front panel to the mounting tray with four of the included #6
screws.
13 . If desired, tear out one of the four perforated self-adhesive overlay sheets and
apply it to the underside of the mounting tray.
