NOTE: The aluminum Strong-Back has been factory cut-to-length for use with US Solar
Mounts supplied solar panels. If another source of module is used, the beam may need to be
trimmed to a shorter length. Most 60-Cell modules will have their holes spaced between 36
”
and 44
” apart. Both ends of the Rail will need to be trimmed to ensure the Pivot Hole remains
centered. A standard miter saw may be used to cut the aluminum.
Remember to secure/clamp the workpiece and CUT SLOWLY.
To calculate: Strong-Back Length = Module Hole-to-Hole center
di 1.5”
If you have any questions at all, please give us a call & we will help you with it.
1. Set the Strong-Back into the Slip-Fitter Assembly as shown below. Line up the holes and
insert the ½”-13 Pivot Bolt through the Slip-Fitter and Strong-Back. Hand Tighten ONLY.
The Rail needs to be able to pivot in order to set the array elevation later.
2. Slide the pre-assembled Angle Brace Bracket into the bottom
North
end of the Strong-
Back as shown.
3. Remove the bolt from the lower end of the Brace Arm.
4. Swing the Angle Brace upward so that the lower end can be fastened onto the Angle Brace
Mounting Tab on the North side of the Slip-Fitter Assembly.
5. Insert the bolt (previously removed) back through the lower hole in the Brace Arm and
mounting tab. Tighten the nut/bolt only finger-tight at this time.
6. Tighten the Angle Brace Bracket bolts just tight enough to hold the StrongBack in place
for assembly.
