Front and rear waterfalls allow for equipment patching and server patching. All styles of Mighty Mo 20 vertical managers can be mounted front or rear and airflow baffles can be mounted to manage the airflow of side breathing equipment.

Note: Static capacity 2,000 lbs. Assembly required. Replace the "X" tail code with "B" for black or "W" for white.

  • Front profile matches the Mighty Mo 20 channel racks and the rear has an additional waterfall for server cable routing: Provides a unified, streamlined look throughout the row of racks and allows both styles to share vertical management.
  • The mounting rails adjust from 12.5" to 36" or 42" depending on rack size, independent of the structural members: Allows the rails to be adjusted after the rack is installed.
  • Choice of vertical management can be mounted front or rear: A solution for every application; vertical cable management cage with individual rack unit fingers and hinged slam latch door, vertical cage with individual rack unit fingers and snap on covers, vertical cage with hinged latches, and individual cable management rings.
