Installation Guide
Step 1: Install the Mounting Sleeve on Vertical Pipe
Step 2: Install the Strongback to the Mounting Sleeve
Before installing the Mounting Sleeve, verify that the Mounting Pole is plumb to
the ground and hasn't shifted or leaned while the concrete footing has cured.
The Mounting Sleeve slips on top of the Mounting Pole and has two 3/8” Set Bolts
which are used to secure it to the Mounting Pole. (See Figure 1-1)
A. Slip the Mounting Sleeve on top of Mounting Pole and slide it down until it
rests/bottoms out on top of Mounting Pole.
B. Rotate the Mounting Sleeve so the Support Bar Pivot Tab is pointing north
and the Strongback Vertical Towers are leaning south.
C. Secure the Mounting Sleeve by tightening the two 3/8” Set Bolts.
The Strongback is attached to the Mounting Sleeve using the Pivot Bolt that passes
through its two Vertical Towers and the Support Bar. The Support Bar is attached to
the Strongback on one end and the Support Bar Pivot Tab of the Mounting Sleeve
on the other end using 3/8” hardware.
A. Remove the Support Bar from the Strongback and re-install in the 15
elevation set point. Secure with the hardware and finger tighten. (See
Figure 2-1)
