B-LINE SB5779138YZ – Frequently Asked Questions

1) Will the B-Line SB5779138YZ rack take standard 12-24 rack screws for my patch panels and switches?
Yes. The SB5779138YZ is tapped with 12-24 panel mounting holes on its rails, so standard 12-24 rack screws thread straight in with no cage nuts needed. If your gear ships with 10-32 or M6 hardware, you will need 12-24 screws instead.
2) Is this rack rated for a high seismic area like California?
The SB5779138YZ is built as a Seismic Zone 4 network bay closed duct rack, the highest of the legacy seismic zone classifications. It is also UL Listed. Zone 4 rating applies to the rack itself; the anchorage detail to floor and overhead bracing still has to follow the engineer's drawing for your building.
3) How much equipment will a 75-space open frame rack actually hold?
75 mounting spaces on the SB5779138YZ works out to 25 rack units of gear (three holes per RU), so you can plan around 25U of switches, patch panels and cable management in the bay.
4) What steel and gauge is this open frame rack made from?
Steel, 11 gauge, to ASTM A1011SS structural quality sheet. That is the heavy end of rack framing material and is what carries the Seismic Zone 4 duty.
5) What does the 'closed duct' and 'top channel' construction on this B-Line bay give me?
It is a network bay closed duct rack with a top channel style top, so the frame includes an enclosed vertical duct for routing and protecting cable, and the top channel gives you a continuous member at the head of the bay for tying into overhead cable runway or bracing. If you just need a plain two-post relay rack for a few switches, an open frame rack without the closed duct is the simpler buy.
6) Is the B-Line SB5779138YZ an enclosed cabinet or an open rack?
Open frame, not an enclosure. There are no side panels, no doors and no locks, so equipment is accessible from all sides. If you need physical security or airflow containment in a shared space, a lockable enclosed cabinet is the right product instead.
7) What exact part number do I order for this Eaton B-Line seismic network bay?
Order Eaton B-Line part number SB5779138YZ. That single number covers the 138 inch, 23 inch wide, yellow zinc, 75-space Zone 4 closed duct bay with 12-24 rails; there are no separate finish or size options to specify.
8) Is a yellow zinc finish acceptable for an exposed data room, or should I look for black?
The SB5779138YZ comes in yellow zinc only. Yellow zinc is a plated, corrosion-resistant finish typical of structural telecom framing and is normally specified for back-of-house telecom and equipment rooms rather than finished, customer-visible spaces. If the rack sits in a visible area and the spec calls for black, this finish will not match.
9) How heavy is this rack and can two people set it in place?
It weighs 136 lb bare. At 136 lb and 138 inches tall it is a two to three person lift at minimum, and the length makes it awkward in stairwells and elevators. Plan on rigging it into the room before any equipment goes on the rails.
