2.3.2 BUC Round Pole Mounting Instructions
1. Position the BUC and mounting brackets facing upward. Position (2) 14”
Unistrut channels centered on the converter mounting brackets. Fasten with 1/4”
hardware (4 to 6 each of bolts, split and flat washers).
Note: Vary the number and location of the hardware as needed to avoid
interfering with the spring nuts used for the pipe blocks.
2. Position two spring nuts into the channel of one of the remaining Unistrut
channels. With the mounting holes facing the ends of the channel, fasten two
pipe blocks loosely to the spring nuts with the hardware
(2 each 5/16” bolts, split
and flat washers).
3. Place the channel with pipe blocks against the mounting pole, slide the pipe
blocks until they contact the mounting pole. Ensure the pipe blocks are centered
to the Unistrut and tighten the hardware. Use this channel as a guide and mount
the pipe blocks on the remaining three channels in a similar manner.
4. Position two spring nuts in each of the Unistrut channels mounted to the BUC.
Position these nuts between the pipe blocks and the ends of the Unistrut.
Note: Above the spring nuts, position the flat fitting plates with the locating
notches engaged in the openings of the channels.
5. Thread a 5/16” nut, split and flat washer onto each of the threaded rods, leaving
1” of rod remaining. Thread that end of the rod through the flat fitting plates and
fully into the spring nuts (do not bottom out). Using one of the mating channels,
ensure that the threaded rods from the channels mounted to the BUCs are
aligned with holes in the mating channels. Center these rods with the channels as
well as possible and tighten the hardware.
6. Thread a 5/16” nut, split, flat washer and flat fitting plate on the remaining ends
of the threaded rods. This hardware is to secure the mating Unistrut channels
from the opposite side of the pole to the threaded rod. Adjust accordingly.
7. Position the BUC with the pipe blocks against the pole, slide the mating Unistrut
channels onto the threaded rods from the opposite side (pipe blocks against pole
and channels against flat fitting plates). Adjust and fasten with the
5/16”
hardware (4 each flat, split washers, and nuts).
