B-Line Eaton series open racks, 102.375" height, 17.875" length, 10" width, Aluminum, RCM rack mounted double sided vertical cable manager cover, Dir

Plan on 10 inches of width and 17.875 inches of depth for the manager channel itself. That 10 inch channel is the wide option for runs with heavy cable counts, and the 17.875 inch depth needs to be matched against the depth of the open frame rack it bolts alongside so the front and rear faces line up.

Yes, it is built for direct PDU mounting, so a vertical rack PDU fastens straight into the manager body instead of eating a rack unit up front or needing a separate bracket kit.

The required number of gates and the mounting hardware ship with it, so you are not sourcing fasteners or door gates separately. The gates are low density plastic, which suits openings where cable volume varies run to run rather than a fixed high-count bundle.

Double sided. The RCM rack mounted double sided vertical cable manager cover organizes cable on both the front and rear faces of the rack, which is what you want when patch panels face forward and switch cabling terminates at the back of the same frame.

It carries UL certification, which is typically the first line item a facilities or institutional spec sheet asks for on rack accessories going into a telecom or electrical room.

Go to the 10 inch width when cable counts vary or grow, which is exactly the use case this B-Line manager is specified for. A narrower channel is fine for a fixed, light patch count, but once you are stacking high-density copper plus a vertically mounted PDU in the same channel, the 10 inch width plus the 17.875 inch depth gives you the bend radius and room the narrower option does not.

Finish is flat black powder coat with black plastic components, so it reads as matte black rather than gloss. If your existing racks are a flat black powder coat, it will blend; against a gloss or textured black cabinet there will be a visible sheen difference.
