how to install Middle Atlantic 27RU Rackrails for ERK Series Racks

• Identify the exact position for the rails on each side of the rack, ensuring the 27U height is accounted for and that both rails will run parallel to each other for proper equipment alignment.
• Engage the rails with the rack’s 10-32 threaded holes. If your ERK rack requires cage nuts or additional hardware, install those first according to your rack’s specifications to ensure a secure, stable mounting surface.
• Attach each rail to the rack side panels using the supplied 10-32 fasteners or the hardware recommended by your rack manufacturer. Tighten evenly to prevent skew or misalignment that could affect equipment installation or operation.
• Verify rail parallelism and depth alignment before introducing equipment. A quick check with a level or straightedge helps ensure a clean, secure fit and smooth sliding of rack-mounted gear.
• Install your equipment into the rack rails, guiding it carefully to engage with the mounting holes. Secure the equipment using the appropriate screws or mounting hardware for the equipment’s chassis mounting tabs, ensuring firm, vibration-free mounting.
• Close and secure the rack doors or enclosure, then perform a final inspection to confirm that all fasteners are tight and that the equipment sits evenly without interference from adjacent units.
