B-LINE SB5856138UTG – Frequently Asked Questions
1) Is this B-Line rack approved for a Seismic Zone 4 installation?
It is built as a Seismic Zone 4 open duct unequal flange rack, which is why the frame is a heavier steel section than a standard open rack. The seismic rating depends on the rack being anchored per the engineer's detail, so floor anchorage and any top bracing to overhead structure still have to be provided on site. The rack itself is UL Listed.
2) What does "unequal flange" mean on a telecom rack, and why would I pick it over a standard rack?
Unequal flange means the two legs of the upright channel are different widths, giving you a deeper mounting face on one side. On an open duct telecom rack that extra flange depth is where vertical cable management and duct attach, and it is part of what carries the seismic load. If you are just stacking a few network switches in a light-duty closet, a standard equal-flange open rack or a wall-mount frame is simpler. Choose this one when the spec calls for Seismic Zone 4 and open duct cable routing.
3) What is the footprint and weight of the SB5856138UTG rack?
The frame is 23 inches wide and weighs 107.13 lb bare. Plan the lift for two people and check your floor loading once populated, since 75 spaces of switches, patch panels and power strips will add many times the frame weight. The 23 inch width is the frame itself, not your aisle clearance, so allow working space front and rear.
4) Does the top channel style on this rack let me tie into overhead cable tray or ladder rack?
Yes, it is a top channel style frame, meaning the uprights are joined by a channel across the top rather than being open-topped. That channel is the attachment point for overhead ladder rack and runway, and on a Seismic Zone 4 installation it is also where top bracing to the building structure is made.
5) What is the exact part number to order this B-Line 138 inch open rack?
Order by Eaton B-Line model SB5856138UTG. That covers the 138 inch high, 23 inch wide steel frame with 12-24 tapped universal spacing, 75 mounting spaces, top channel, telco gray powder coat.
6) Will telco gray match the racks already in my equipment room?
The finish is a telco gray powder coat, the standard color for central office and telecom equipment frames, so it lines up with existing telco-gray B-Line and most other carrier-spec racks in the room. Powder coat on steel also holds up better than paint in an MDF or industrial space where carts and ladders knock the uprights.
