Aligning the Outer Rails

Note: If installing in a D-Rack with the D-Rack Stiffener (see
vertical bolts loose. Then, using the small screws provided, attach the outer rail to the D-Rack
Stiffener and secure the screws firmly. Make sure the screw heads are counter-sunk, so as not to
catch on anything rolling in the rack. The vertical bolts in the D-Rack Stiffener will allow the rails
to be adjusted later using the alignment tool.
3. Use the long phillips screwdriver to fasten the rear screws of the rail to the rack. Keep the
screws loose for later adjustment.
4. Attach the rail to the rack at the front using the screws provided, keeping them loose for later
adjustment.
Important: These steps must be taken or the wheels of the inner rail can get bound to the outer
rail, causing the chassis to get stuck.
1. Tighten the screws on the left rail completely: middle bolts first (for D-racks), then the front
screws, and lastly, the rear.
2. Using the included alignment tool, insert it into the rails so that it rests on the inner track of
the outer rails, just as a chassis would.
3. Adjust the right rail until it is flush with the alignment tool and the left rail. Insure that the
tool can be slid smoothly from the front to rear of the rack. This step is also best
accomplished with two people, as shown in
