B-LINE SB5774140YZ – Frequently Asked Questions

1) Is the B-Line SB5774140YZ rack rated for a Seismic Zone 4 installation?
Yes. The SB5774140YZ is built as a Seismic Zone 4 network bay closed duct rack, so it is the version to spec where the structural drawings call for Zone 4 anchorage. It is also UL Listed. Anchorage hardware and the floor attachment detail are a separate part of the job from the rack itself.
2) How many rack units does the B-Line SB5774140YZ open frame rack give me?
It provides 58 mounting spaces on the rails, on a frame that stands 140 inches tall. That is a tall-bay rack, so check your ceiling height, cable tray elevation, and sprinkler clearance before ordering.
3) What hole pattern are the mounting rails on the SB5774140YZ, and will my equipment bolt straight in?
The rails are punched with 12-24 panel mounting holes. Equipment mounting with 12-24 screws or 12-24 cage-free tapped rails drops straight in; gear supplied for 10-32 or square-hole cage nuts will need the matching screws or an adapter rather than the ones that ship with it.
4) Is this B-Line rack a standard 19 inch EIA rack?
The frame width is 19 inches, which is the standard equipment mounting width for switches, patch panels, and rack-mount servers. It is an open frame rack, not an enclosed cabinet, so there are no side panels or doors.
5) Open frame rack or an enclosed cabinet for a telecom room?
An open frame rack like the SB5774140YZ is the right call in a secured, dedicated telecom or equipment room where you want full access on all four sides, easy cable dressing, and free convection airflow. Go with an enclosed cabinet instead when the space is shared, publicly accessible, or dusty, or when you need lockable doors and directed front-to-back airflow. This one adds a closed duct top channel for cable management above the bay.
6) What is the finish on the B-Line SB5774140YZ, and is it suitable for grounding and bonding?
Steel frame with a yellow zinc plated finish. Yellow zinc is a conductive plating rather than a paint film, which is why it is commonly specified in telecom bays where the rack itself is part of the bonding path. Bonding lugs and busbar are ordered separately.
7) How heavy is the SB5774140YZ rack for planning delivery and setup?
137 pounds for the frame, standing 140 inches tall. Plan on two people and a lift or boom for the stand-up, plus overhead clearance to rotate it upright in the room.
8) What is the exact part number to order this Eaton B-Line seismic network bay rack?
Order it as Eaton B-Line part number SB5774140YZ. That number covers the steel, yellow zinc, 140 inch, 19 inch wide closed duct rack with 12-24 rails and 58 mounting spaces.
