B-Line Eaton series open racks, 5.9" height, 8" length, 19" width, Steel, RCM rack mounted single sided horizontal cable manager, Plastic finger, Sil

Yes. The B-Line SB87019SX4SL is a rack mounted horizontal cable manager built at 19 inches wide, which is the standard EIA rack mounting width, so it bolts to the front rails of a standard 19-inch open frame rack or cabinet. It stands 5.9 inches high and projects 8 inches in depth, so allow for that depth in front of the rails when you lay out the elevation.

At 5.9 inches of panel height it occupies roughly 3.4 rack units, since one RU is 1.75 inches. Practically that means you need to leave a 4U opening in the elevation for it rather than assuming it drops into a 3U gap.

Single sided. The RCM unit routes cable on one face only, so it is intended for the front of the rack where patch cords come off the panels. If you need cable managed on both the front and rear faces of an open frame rack, plan on a manager for each side.

That is what they are there for. The plastic finger style manager controls bend radius as cable passes through it, which is the requirement that matters most on fiber jumpers and on high pair-count copper where a tight bend degrades performance. The fingers are black plastic on a silver powder coated steel body.

It carries UL certification, which is usually what a facility or institutional spec calls for on rack-mounted raceway and management components. The part number to reference on a submittal is Eaton B-Line SB87019SX4SL.

Use the horizontal RCM unit for the short runs between patch panels and switches inside the same rack, where the job is turning cords sideways without kinking them. Vertical managers mount on the side of the rack and are the right choice when you need greater overall cable capacity and a path from top to bottom of the frame. Most open frame builds use both: horizontals every few panels, verticals on each side for the trunk.

The body is 14 gauge steel with a silver powder coat finish and black plastic finger components. Powder coated steel at 14 gauge is a heavier gauge than the light sheet used on many patch-panel accessories, so the unit carries loaded cable bundles without deflecting. Total weight is 4.4 pounds.
