B-LINE SB58901AFB – Frequently Asked Questions

1) Will the B-Line SB58901AFB guard rail fit a standard 19 inch two-post equipment rack?
Yes. The SB58901AFB guard rail is built at 19 inches wide, which is the standard EIA rack mounting width, and it is intended for two-post network equipment racks. It mounts with 3/8"-16 hardware, so the rack rails need to be tapped or punched for 3/8"-16 rather than 12-24 or cage nut.
2) What mounting hardware thread does the SB58901AFB use?
3/8"-16. That is the heavier threaded hardware used on many Eaton B-Line two-post open frame racks, not the 12-24 or 10-32 threads found on lighter racks. If your uprights are tapped 12-24, this rail will not thread into them.
3) How much rack space does the B-Line SB58901AFB guard rail take up?
It occupies 2 rack mount units (RMUs) of vertical mounting space, and the part itself is 2 inches high with a 4.25 inch depth. Budget those 2U in your elevation drawing before you lay out active gear.
4) Is this rack guard rail aluminum or steel, and will it hold up in a humid or coastal MDF room?
The SB58901AFB is aluminum with a flat black powder coat finish. Aluminum with a powder coat does not rust the way bare steel does, which is why it gets used in telecom closets and equipment rooms where humidity is a concern. At 1.5 lb it also adds almost nothing to the rack load.
5) What does a guard rail actually do on an open frame two-post rack?
On a two-post open frame rack, gear and cabling are exposed on both sides. The SB58901AFB guard rail bolts across the rack to give a physical barrier at that point in the elevation, taking 2 RMUs of the mounting space. It is an accessory for the Eaton B-Line open frame rack line, not a rack or a shelf on its own, so you order it in addition to the rack.
6) What is the exact part number to order this Eaton B-Line guard rail?
Order it as Eaton B-Line SB58901AFB. That single part number covers the aluminum, flat black powder coat, 19 inch, 2 RMU two-post rack guard rail. There are no finish or size options to specify with it.
