B-Line SB87019DX2SL Eaton series open frame racks, 2.4" height, 17.1" length, 19" width, Steel, RCM rack mounted single sided horizontal cable manager, Plastic finger, Silver powder coat

Yes. The SB87019DX2SL is built at 19 inches wide, which is the standard EIA rack mounting width, and it is intended as a horizontal pathway on a two post rack. At 2.4 inches tall it occupies the space of a little over one rack unit (1U is 1.75 inches), so plan for 2 RU of clear panel space between your patch panels or switches.

Single sided. The B-Line RCM horizontal manager routes cable on the front face only, with plastic fingers holding the bundles. If you need managed cable on both the front and rear of a two post rack, you would order two of them, one on each side of the rack rails, or move to a double sided manager.

The body is 14 gauge steel with a silver powder coat, and the cable fingers are black plastic. Heavy gauge steel with a powder coat is what you want for an open frame rack in an MDF or IDF closet, and the whole unit only weighs 3.9 pounds so it adds essentially nothing to the rack load.

The SB87019DX2SL comes in silver powder coat, which is the standard silver/grey finish used across the Eaton B-Line open frame rack line. The visible fingers are black plastic, so expect a silver frame with black cable fingers rather than an all-silver face. If your rack room is standardized on black, this is not the finish match.

Common practice is one horizontal manager directly under each patch panel so the jumpers break out cleanly instead of draping across the panel below. The B-Line RCM is made for exactly that spot on a two post rack, and its design keeps cabling access open to the back of the patch panel so you can still reach terminations after the jumpers are dressed in. Count one 2.4 inch manager per panel when you lay out rack elevations.
