B-Line Eaton series open racks, 84" height, 12.5" length, 3.65" width, RCM high density cable managers, Flat black powder coat

The SB86163DFB RCM high density cable manager stands 84 inches tall, 3.65 inches wide, and 12.5 inches deep. That 3.65 inch width is what you need to allow between rack uprights or between a rack and a wall when you lay out the row, and the 84 inch height matches a standard full-height open frame rack so the manager runs the full face of the rack.

It is built for Eaton B-Line series open frame racks and is listed as compatible with RCM cable managers, at the same 84 inch height as a full-height open rack. If your uprights are a different height or a different manufacturer's frame, confirm the hole pattern on your rack before committing, because the fit stated here is to the B-Line series open frame rack.

The manager has multiple cable passthrough openings along its length plus cable tie lances, so you can route jumpers out to patch panels or switches at whatever RU you need and tie the bundle off to the lance instead of relying on the fingers alone. That matters on a high density fiber or Cat6 row where bundle weight would otherwise sag onto the terminations below.

At 3.65 inches wide the SB86163DFB is a narrow vertical section, which suits the end of a row, a two-post rack in a tight closet, or a run where you only need to carry jumpers a few RU. For a fully loaded 48-port-per-RU patch field where every port is populated, the jumper volume usually calls for a wider RCM section between racks instead. Count your jumpers and bend radius before settling on the narrow width.

Finish is flat black powder coat, and the color is black. It is the same flat black used across the Eaton B-Line series open frame rack line, so it reads consistently next to black racks rather than showing a gloss difference down the row. Powder coat also holds up better than paint to cable pulls scraping the edges over time.

21.4 pounds for the SB86163DFB. It is a full 84 inch section, so the weight is manageable for one person but the length is awkward alone against a standing rack. Most techs set the top fasteners first with a second pair of hands, then work down.
