Track Installation
Refer to Figures 4, 5, and 6 for the following instructions.
1. Measure the distance between the front and rear rails (depth between the front and rear
vertical rails can be no less than 22 inches and no more than 28 inches).
2. Attach a rear mounting bracket to each stationary track section. Use two 10-32 x 3/8 inch
pan head screws and one bar nut for each assembly. Choose an alignment to match the rail
spacing. Do not fully tighten the screws. The front rail mounting method is shown in Figure
5. Figures 6a and 6b illustrate the rear rail mounting methods for deep and shallow racks,
respectively.
3. Install the stationary track assemblies into the rack. Use four 10-32 x 3/8 inch pan head
screws to secure each track assembly to the rack rails. Use bar nuts if the rack rail holes are
not threaded. Tighten the rack rail screws enough to secure the stationary track assemblies to
the rack while still allowing movement. Fully tighten the screws that attach the rear
mounting brackets to the stationary sections.
4. Slide the intermediate track sections into the stationary tracks so they lock in their extended
positions.
5. Carefully lift the mainframe into place so the chassis track sections align with the
intermediate track sections. Slide the chassis tracks into the intermediate tracks and push the
mainframe halfway into the rack. It will stop at the first detent.
6. The sliding track sections should align themselves as the mainframe is pushed into the rack.
Tighten all loose screws.
If the tracks do not operate smoothly, loosen the screws that secure the stationary track sections
to the front and rear rails. Center the mainframe assembly, allowing the tracks to seek their
proper position, then retighten the screws.
The tracks require no lubrication because of their special finish.
