Installation Guide

Step 1: Measure and Mark Rail Bracket Positions
Step 2: Attach Rail Brackets to the Strongback
Using a tape measure, square, and marker, carefully measure and mark the Rail
Bracket positions on the face of the Strongback.
A. Refer to the Rail Bracket Spacing Chart. Locate the Module Type to be used in
your installation and find the corresponding “A” and “B” measurements.
B. First mark the “A” dimension on either side of the Strongback Pivot Hole.
From the center of the Pivot Hole, measure outward on both sides of the
Pivot Hole and draw a line establishing dimension “A”. (See Figure 1-1)
C. Next, measure and mark the “B” dimensions on either side of the Pivot Hole
by measuring from the “A” reference lines established in the previous step.
Rail Brackets are secured to the Strongback using 3/8” x 7/8” inch Track Bolts and
Flange Nuts. Care must be taken to properly orient each Rail Bracket to marks “A
& B” made in the previous steps. See Figure 2-1 for proper orientation.

NOTE:
Be precise in
measuring,
marking and
installing the Rail
Brackets. Improper
installation will lead
to misalignment
issues when
installing PV
Modules.
