Step 3
There are four bolts and nuts per module. Pre-
mount the module bolts so that the serrated nuts will
dig into the underside of the module frame.
Do not tighten the bolt fully. Leave it about one full
turn loose so it will glide easily in the module track.
Step 4
Measure and record the "center to center" distance
of the intermediate mounting holes. This dimension
sets the spacing of the mounting rails.
Each pair of mounting rails typically holds from 3 to 4
large modules. Typical rail spacing might be from
24" to 35" apart.
Step 5
Remove a pair of modules rails from the frame
bundle. They will be bolted on top of the torque tube
so that the "legs" of the channel face inward towards
each other.
The bolts on in the top track are the module
fasteners and the bolts in the side track secure the
module rail support angle.
