KNOCK-OUTS

To accommodate fans or wire pass through, there are (2) 120mm-diameter

cut hole patterns in both the top and bottom plates of the rack. To remove,

simply use a hammer to knock the plates out and remove. Do not remove

more than one knockout from each plate.
* If running wires through holes is needed when stacking two racks

together, remove the same knockout from both the top and bottom plates.

OPTIONAL FEET (Included with Rack Hardware)

Also included are 4 hard plastic, stationary feet. If casters are not desired,

simply unscrew casters and use stationary feet instead.
CAUTION - feet may damage flooring if rack is moved when loaded

with equipment.

ACCESSORY INSTALLATION

• Determine the layout of your components, their space requirements

and where you will place vents or blanks.
• Unbox your first shelf, starting with the one you will place at the bottom

of the rack. The heaviest components should be placed as low as possible.
• Unfold shelf side panels and mount in desired rack location using four

Strong™ rack screws. Accessory mounting screws are not included with

shelves, vents or blanks (only with racks).
• Install component onto shelf.
• Unbox and install the next shelf, vent or blank following the above steps.

A vent should be placed above components that generate excessive heat,

such as surround receivers, amplifiers, satellite receivers, DVR’s, cable boxes

and media servers.
