Middle Atlantic EVO 45 Cable Guides - EFB45-CMG

Middle Atlantic EFB45-CMG EVO Series Cable Guides

Overview

The Middle Atlantic EFB45-CMG is a cable management guide accessory designed for use with Middle Atlantic's EVO Series rack enclosures. Cable guides serve a specific, unglamorous purpose that pays off during every service call: keeping patch cables, power runs, and signal wiring routed predictably inside the rack so technicians can trace, add, or replace a cable without disturbing adjacent equipment. Proper horizontal cable management like the EFB45-CMG prevents cable sag into ventilation paths and reduces stress on rear-panel connectors — both common failure sources in dense AV and security rack builds.

Compatibility

The EFB45-CMG is engineered for Middle Atlantic's Middle Atlantic EVO Series rack enclosures. The '45' in the part number references the 45U enclosure family. Verify fit against your specific EVO enclosure model before ordering — Middle Atlantic's EVO line spans several frame depths and widths, and cable management accessories are frame-specific. If you are building out a full rack accessory kit, confirm the guide quantity needed per rack U-count and planned cable density. For multi-rack deployments in AV control rooms or NVR equipment rooms, plan one guide per major cable bundle break-out point rather than spacing by U alone.

Installation Notes

Cable guides in the EVO line are typically tool-free or single-fastener snap-in accessories that attach to the vertical frame rails. Route cables through the guide fingers before final dressing — attempting to thread a pre-dressed bundle through a mounted guide is the most common installation error. Leave service loops on every cable that connects to a slide-out shelf or drawer; the EFB45-CMG manages the run but does not compensate for insufficient slack.
