B-Line SB5776084TG Eaton series open frame racks, Steel, Telco gray powder coat, 12-24 panel mounting holes, 58 mounting spaces, Top channel style, Seismic Zone 4, network bay open duct rack, Grade 33, ASTM A570

Yes. The SB5776084TG is a 19 inch wide open frame rack, so standard 19 inch EIA panels and equipment mount to it. The rails are punched with 12-24 panel mounting holes, which is the tapped thread most telecom and network gear uses, so you screw directly into the rail without cage nuts.

58 mounting spaces on an 84 inch tall frame. That is usable panel space for switches, patch panels and rack-mount servers. If you are laying out a room, count 58 RU per bay when you size how many frames you need.

The SB5776084TG is built as a Seismic Zone 4 network bay open duct rack, which is the highest seismic zone classification and the one that applies to most of California. Anchoring to the slab per the structural drawings is still on the installer.

Yes, it carries a UL Listing. For a data room or an inspected commercial build that is usually what the AHJ wants to see on the equipment rack itself, alongside the bonding and grounding details.

ASTM A570 Grade 33 steel throughout, finished in Telco gray powder coat. Grade 33 refers to a 33 ksi minimum yield, which is what lets the frame carry loaded equipment and still meet the Zone 4 classification.

Plan on two people. The frame weighs 118 lb and stands 84 in tall, so it will not stand upright through a standard 80 inch door opening. Walk it in laid down or on a cart and stand it up in the room.

An open duct rack like the SB5776084TG gives you access from all four sides and free airflow, which is why it is the standard in secured telecom and MDF rooms where the door itself is the security. Choose an enclosed cabinet instead when the equipment sits in a shared space, a warehouse, or anywhere you need lockable doors and dust control. The open frame also makes vertical cable management and duct routing far easier on high density patching.

No. The rails on the SB5776084TG are punched 12-24, so 10-32 hardware will not thread correctly and will strip the hole. Order 12-24 rack screws and cage-nut-free mounting hardware to match.

The SB5776084TG is a top channel frame, meaning the rack is capped with a channel at the head rather than an open pair of uprights. That channel is what you tie ladder rack or overhead cable runway to, and it stiffens the bay when racks are ganged in a row.
