B-LINE SB5771140YZ – Frequently Asked Questions

1) Will the B-Line SB5771140YZ rack fit a standard 19 inch network panel?
Yes. The B-Line Eaton series SB5771140YZ open frame rack is a 19 inch wide rack with 12-24 panel mounting holes on the rails, which is the standard EIA rail thread for network and telecom panels. It gives 51 mounting spaces (rack units) of usable height.
2) Is this B-Line rack rated for a Seismic Zone 4 installation?
The SB5771140YZ is built as a Seismic Zone 4 network bay closed duct rack, from 11 gauge steel. It is also UL Listed. Seismic performance still depends on anchoring it to the slab per the engineer's detail, so the frame rating is one half of the job.
3) What does a closed duct network bay rack do that a plain open rack does not?
A closed duct bay routes cable inside the rack uprights rather than leaving it exposed on the outside of the frame, which is what telecom bays in central office and MDF rooms are specified for. The SB5771140YZ pairs that closed duct construction with top channel style, so it is intended to tie into an overhead cable runway system rather than stand alone.
4) Do I need 10-32 or 12-24 screws for this B-Line rack?
12-24. The mounting rails on the SB5771140YZ are punched with 12-24 panel mounting holes, so order 12-24 rack screws and washers. 10-32 hardware will not thread correctly and is the most common mis-order on telecom bays.
5) How heavy is the SB5771140YZ rack for handling and floor loading?
The frame itself weighs 137 lb empty. At 140 inches tall that is an awkward two-person carry and it should be stood and anchored before any equipment goes in.
6) Is the yellow zinc finish on this rack suitable for a damp or unconditioned room?
The rack is steel with a yellow zinc surface finish, which is a plated corrosion-resistant finish intended for indoor equipment rooms. For outdoor or wash-down environments you want a different finish; yellow zinc is not an exterior coating.
7) What is the exact part number to order this Eaton B-Line rack?
Order model SB5771140YZ from the Eaton B-Line open frame rack series. That number covers the steel, yellow zinc, 140 inch, 51 space closed duct seismic bay.
