B-Line Eaton series open racks, 102.375" height, 21.625" length, 3.625" width, Aluminum, RCM rack mounted vertical cable manager double sided, Direct

Double sided means the channel carries cable on both the front and the rear of the manager, with plastic gates on each face. You get double the cable capacity of a single sided unit and can keep patch cords on one side and power or uplinks on the other. If you only need to dress cable on the front of an open rack, a single sided manager is the cheaper, shallower choice.

Yes. The RCM manager is built for direct PDU mounting, so a vertical rack PDU fastens straight to the manager body instead of needing a separate bracket kit or consuming rack RU. That is the main reason data center and MRO buyers pick this version over a plain cable channel.

UL is the certification carried on the B-Line SB86083D108SL vertical cable manager, which is typically what a facility or institutional spec calls for on rack and enclosure hardware. No fire rating or other listing is claimed beyond that.

Push in fasteners and a cable strap mount ship with the unit, so the gates and basic cable retention are covered out of the box. Anything else for the job (rack-to-manager bolts beyond what is supplied, ladder rack transitions, the PDU itself) is separate.

It will not. The finish is silver powder coat with black plastic components on an aluminum body. If your row is all black, this unit will read as a mismatch down the aisle; look for the black finish version of the same RCM manager instead.

The low density gate style uses fewer, wider-spaced plastic gates along the channel. Cable goes in and comes out fast, which suits moves and changes, but it holds bundles less tightly than a high density gate arrangement. For a patch field with heavy churn, low density is the easier one to work in; for a dense, permanently dressed bundle a high density gate holds the form better.

The body is aluminum with a silver powder coat, which keeps the 102.375 inch unit down to 39.9 lb while resisting corrosion in a conditioned equipment room. It is a cable and PDU management member, not a load-bearing part of the rack frame, so equipment weight still rides on the open frame rack itself.
