Method 2: Take a look at the layout drawing provided in the instruction packet. There is
a dimension showing the distance from the cut end of the Extruded Rail to the
centerline location of the Rail Slider. With the Extruded Rail in the correct orientation –
the 3/8” slot facing the outside edge of the Rail Slider, and either the 1/4” or 5/16” slot
on top (depending on hardware used) – mark a line.
Pre-Installing Mounting Hardware
•
Now that the Extruded Rails have been marked,
slide the provided module mounting hardware (1/4”
or 5/16” x 5/8” hex bolts) into the tracks at the
approximate mounting locations. It is only necessary
to locate the bolts in the general area of the module
frame holes – this will make the installation of the
modules easier. Also slide two 3/8” round head bolts
to the center of the marked lines.
Installing Rails on Truss Tubes
•
Using the marked lines as a guide, align the Extruded Rail to the Rail Sliders. Install
one flat washer and Nylock nut. Loosely tighten the nut.
•
In the process of installing the rails, use a measuring tape to verify that the rails are
square and parallel with the rack.
