Installation
Assemble the Adjustable Depth Server Rack
The Adjustable Depth Rack features Front and Rear Horizontal Brackets that can be
set to the required mounting depth. The Adjustment Holes on the brackets are spaced
1 inch (2.5 cm) apart. The minimum depth is 12 inches (30. 5 cm ) and the maximum
depth is 20 inches (50.8 cm).
Assemble the Bracket Assemblies
1. Prepare Bolt Assemblies (x 12) for use in Step 4 by sliding the Washers (x 12) over
the Bolts (x 12).
2. Determine the Required Mounting Depth according to your application.
3. Slide one of the Rear Horizontal Brackets into one of the Front Horizontal
Brackets. Slide these two components together until the Required Mounting Depth
has been achieved and the Adjustment Holes are aligned on the two brackets.
4. Insert the Bolt Assemblies through the Adjustment Holes, two on the side and one
on the horizontal surface, on the aligned Front and Rear Horizontal Brackets from
Right Mounting Rail
