B-LINE SB5878138TG – Frequently Asked Questions

1) Will the B-Line SB5878138TG rack fit standard 19-inch rack-mount equipment?
The SB5878138TG is a network bay closed duct rack with 12-24 tapped panel mounting holes and 75 mounting spaces, and it measures 23 inches wide overall. Standard rack-mount gear with 19-inch panels and 12-24 hardware mounts directly to the rails; overall frame width runs wider than the panel itself, which is normal for an open frame rack.
2) Do I need 12-24 screws or 10-32 screws for this Eaton B-Line network bay rack?
Order 12-24 hardware. The rails on the SB5878138TG are tapped 12-24, so 10-32 screws and cage nut kits will not thread into them. Budget screws for the full 75 mounting spaces if you are loading the bay out completely.
3) Is this B-Line rack rated for a Seismic Zone 4 installation?
Yes. The SB5878138TG is built as a Seismic Zone 4 network bay closed duct rack, so it is the version to specify where the drawing calls for Zone 4 anchorage. It is also UL Listed.
4) How much equipment weight can this open frame rack carry?
Load capacity on the SB5878138TG is 200 lb. That is the limit for the gear you hang on it, and the frame itself weighs about 151.98 lb empty, which matters when you are calculating anchor loads for a seismic install.
5) What gauge steel is this Eaton B-Line rack made from?
Frame steel is 11 gauge to ASTM A1011SS. That is the structural sheet spec behind the 200 lb load rating and the Seismic Zone 4 designation, and it is what a submittal reviewer will be looking for.
6) What does top channel style mean on a network bay rack?
Top channel refers to the channel across the head of the frame on the SB5878138TG. It ties the uprights together and gives you the structural point to land ladder rack, runway, or overhead bracing, which is how a Seismic Zone 4 bay gets braced back to structure.
7) Is the SB5878138TG an open rack or an enclosed cabinet?
It is an open frame rack, not an enclosed cabinet. There are no side panels, doors, or locking provisions, so equipment is accessible from all sides. If you need physical security or airflow containment in a shared space, an enclosed cabinet is the right call instead.
8) Will this rack match the gray finish on the other bays in my telecom room?
The finish is Telco gray powder coat over steel, the standard color used across B-Line series open racks, so a new bay lines up with existing Telco gray equipment racks and ladder rack in the same room.
9) What model number do I order for this Eaton B-Line seismic network bay?
Order part SB5878138TG from Eaton B-Line. That is the 138 inch tall, 23 inch wide, Telco gray, Seismic Zone 4 closed duct network bay with 12-24 rails.
