B-Line SB86083S078FB Eaton series open frame racks, 72.625" height, 21.625" length, 3.625" width, Aluminum, RCM rack mounted vertical cable manager double sided, Direct pdu mounting, Low density plastic gate, Flat black powder coat

At 72.625 inches tall, the SB86083S078FB runs the full height of a standard 7-foot open frame rack, so it mounts flush beside one without overhanging. Footprint is 3.625 inches wide by 21.625 inches deep, so it adds roughly 3-5/8 inches to the bay width and matches the depth of a typical two-post frame. Measure your aisle clearance for that added width before you lay out the row.

Double sided. The SB86083S078FB is an RCM rack mounted vertical cable manager with gates on both the front and rear, giving double cable capacity in one 3.625 inch wide channel. If you only dress cable on the front of the frame, a single sided manager is the cheaper choice; the double sided version earns its width when you run patch cords front and permanent links rear in the same bay.

Yes. The SB86083S078FB is built for direct PDU mounting, so a vertical rack PDU fastens into the manager itself rather than eating rack units in the frame. That is the main reason to spec this model over a plain finger duct.

It uses a low density plastic gate, black plastic components on a flat black powder coated aluminum body. Low density means fewer, wider gate fingers, which suits larger diameter or fewer bundles and makes cable drops easier to open and reseat. If you are managing dense Cat6 patch fields where you want cable retained at tighter intervals, a high density gate style is the better pick.

Push in fasteners and a cable strap mount ship with the SB86083S078FB. Rack mounting screws for your particular frame are not called out, so confirm what your rails take (typically 12-24 or 10-32 on a two-post frame) and add them to the order if you do not have them on the truck.

UL is the certification carried on the SB86083S078FB, which is what most facility and institutional specs ask for on rack accessories. No other rating is claimed for it.

Order it as B-Line SB86083S078FB. That number covers the 72.625 inch double sided RCM vertical cable manager with the low density plastic gate, direct PDU mounting and flat black powder coat finish. Adjacent SB860 numbers change gate density, height or finish, so quote the full string.

Finish is flat black powder coat over aluminum, with black plastic gate components, so it reads as black throughout and sits alongside standard black open frame racks and other black B-Line accessories without a color mismatch. Flat black will not match a gloss black or an anodized clear frame exactly.

14.3 lb bare. Aluminum construction keeps a full 72.625 inch vertical manager light enough for one tech to set and start a couple of fasteners, though a second pair of hands helps hold it plumb against the frame while you land the rest. Loaded cable and a mounted PDU add to what the frame carries, not to the manager's shipping weight.
