B-Line Eaton series open racks, Aluminum, 3/8"-16 mounting hardware, RMUs of mounting space, Flat black powder coat, Two-post network equipment rack

3/8 inch-16 mounting hardware, which is the standard thread on Eaton B-Line series open frame two-post racks. If your rack is tapped 10-32 or 12-24 instead, this rail will not thread into it.

The guard rail measures 23 x 4.25 x 2 inches, with 4.25 inches of length/depth. That projection is what stands off in front of the mounted gear to shield it, so allow for it when you are figuring aisle clearance or planning cable drops down the front of the rack.

On an open two-post frame there is no enclosure panel, so switch faceplates, patch panel ports and cabling sit exposed to carts, ladders and passing traffic. The SB58902AFB bolts across the front and takes the hit instead of the 23 inch equipment behind it. If you want full enclosure and lockable access rather than spot protection, a cabinet is the right choice, not a guard rail.

Order Eaton B-Line part number SB58902AFB. That is the 23 inch, 2 RMU, aluminum, flat black powder coat two-post rack guard rail, and it is the only configuration under that number.

Aluminum, finished in flat black powder coat, and it weighs 1.7 pounds. The light weight means one tech can hold it in place while starting the hardware, and the aluminum avoids adding meaningful load to a floor-standing two-post rack.

The rail is flat black powder coat, the same finish family used on the black Eaton B-Line series open frame racks, so it reads as matte black rather than gloss. For a facility standardizing on black open racks it drops in visually without looking like an add-on part.
